Ideology matters, as I learned from surviving 18 years under the Chavista regime in Venezuela. The United States pretended otherwise for three decades, clinging to the “end of history” and similar dreams. Today, with ideologically driven conflicts simmering around the world, it is time for America to integrate deterrence, defense, and a theory of victory across the so-called gray zone of geopolitics. Doing so will require policymakers to start listening to what America’s enemies have been saying for years about their ideological designs.

In 2004, when questioned about whether a Venezuela-Cuba alliance was exporting communist revolution throughout the Western Hemisphere, the Venezuelan ambassador to the United States averred: “It is a thing outdated in time and it is not understanding the relationships that exist between the countries.” That was a backhanded ‘yes,’ if there ever was one. The message was meant to assuage the busy, post-9/11 national security community, diverting attention away from the problems brewing south of the U.S. border. More than two decades later, the annual warnings of USSOUTHCOM Combatant Commanders before Congress have finally been heeded by the White House.

Ideology has been slapping America in the face since the late 1990s. For this era of refocusing on state-based threats, it comes in these forms and many others: Beijing’s obsession with employing “united front” organizations to silence dissidents overseas; Moscow’s obsession with Ukraine, kicking off a murky war in 2014 that is now sustained conventionally; Tehran’s obsession with aiding and abetting proxy martyrs of the Islamic Revolution; Havana’s and Caracas’ shared obsession with waging “asymmetric war” on Western powers (which included flooding the American homeland with illicit narcotics); and Pyongyang’s obsession with subverting Seoul’s political processes and civic life. All these gray-zone efforts have an ideology at the heart. Their ideologies, variously rooted in Marxism, religion, and revanchism, drive the leaders of these states to employ irregular warfare tactics without any remorse and at any cost to civilians in the West or anywhere else. You will not find high degrees of intellectual coherence between these constructs; shared hatreds and collectivist doctrines and dogmas are cohesive enough for what now amounts to an anti-Western coalition.

Anti-Western adversaries became sneakier when strategizing and aligning with those espousing similar worldviews. They also became more convinced of their moral superiority. The U.S. national security community makes arbitrary distinctions between geopolitics and ideology. These distinctions obfuscate reality, which is already tough to comprehend, and lead to poor policymaking. Nowhere is this weakness more prominent than in the domain of irregular warfare. How did ISIS carve out its domain between Iraq and Syria, for instance, if not through the aid of its ideology?

Discussing rival-state ideology in the Departments of State, Defense, and Homeland Security seems to generate discomfort despite some strides to understand strategic cultures. It started with the spectacular triumphs of 1991. After Saddam Hussein’s defeat in the First Gulf War and the dissolution of the Soviet Union, international relations’ ideological variables have been marginalized in the Federal Government. The American bureaucrat could finally put ‘Sovietology’ to rest, and, with it, anything to do with alternatives to liberal internationalism. The term ‘Great-Power Competition’ continues the delusion; ‘strategic-ideological struggle’ captures reality much better.

Disclaimer: Ideologies are messy. Their study requires incredible levels of nuance, subtlety, cultural awareness, philosophical skill, and extensive interpretive room. It is not a field of expertise attuned nor prone to engineering solutions or linear responses, making it politically dangerous to confront ideological challengers. Bringing up ideology always risks alienating a group and hurting its feelings. Hence, American political leaders and senior officials have scarcely breathed a word about state-centric ideological conflict since the demise of the USSR.

This problematic approach is a vestige of America’s long-gone “unipolar moment.” Through mirror imaging, it takes our attention away from elements that the Western world’s rivals thrive on. Several foes of the West have developed highly complex irregular warfare doctrines, intelligently focusing on the types of operations that some of these actors can excel in, and backing off from the type of war that they know they cannot win. Because illegality is the common denominator to all irregular warfare activities coming from any type of challenger, ideological zeal and fervor are absolute strategic imperatives to the leaders of these revanchist entities. Indeed, during the Global War on Terror, we recognized it as an essential enemy warfighting capability. Ideology is the glue that authoritarians, totalitarians, and other extremists apply to bind together the domestic constituencies that they rely on for control and aggression. In ideology, those leaders find the corpus of thought and the narratives required to morally justify atrocities committed in pursuit of greed, territorial expansion, or a simple clinging to power.

Acknowledgement is growing that defeating mere symptoms of its rivals’ irregular warfare campaigns cannot bring American strategic victory or even achieve deterrence in the “gray zone.” Looking back at the U.S.-led quagmires of Afghanistan and Iraq, more observers have called for defeating root ideologies, rather than just crushing the fighters who currently espouse a certain ideology’s flavor-of-the-moment (e.g., Taliban, al-Qaeda, ISIS, Hezbollah, Boko Haram, al-Shabaab, FARC, ELN, etc.).

Defeating our enemies must include defeating their ideologies. This no longer demands global wars in the traditional (conventional) military sense. To defeat regime ideologies, whole-of-government efforts require dusting off forgotten or atrophied competencies that America used to cultivate, including the ‘dark arts’ of U.S. foreign policy. Washington needs to articulate once again what it believes in, beyond vague notions of stability, and bring like-minded allies to our side.

Why Ideology Matters in Irregular Warfare was originally published on Global Security Review.

Japan and the Republic of Korea (ROK), as key American allies, should strengthen their conventional military capabilities, both offensive and defensive, to reinforce regional deterrence. Two critical steps are needed. First, Japan and South Korea must expand their capabilities to neutralize North Korea’s missile launchers. Second, Japan’s defense architecture should be aligned with South Korea’s Three-Axis System to create an integrated deterrence framework.

So far, to address concerns over potential nuclear decoupling, the US, Japan, and South Korea have explored multiple options. In addition to Washington’s repeated assurances that its nuclear extended deterrence remains intact, discussions have included modernizing American nuclear weapons, expanding nuclear-sharing agreements, redeploying tactical nuclear weapons to South Korea, and even the possibility of South Korea developing its own nuclear arsenal.

However, South Korea acquiring nuclear weapons remains highly improbable due to its significant political costs. From the 1960s to the 1980s, North Atlantic Treaty Organization (NATO) member-states feared the US might hesitate to retaliate with nuclear weapons if the Soviet Union launched a nuclear strike on Europe. While NATO pursued multiple strategies—most notably the dual-key system and the deployment of Pershing II missiles—these measures never fully resolved nuclear decoupling concerns.

Ultimately, NATO never confronted the full extent of this dilemma as the Soviet Union collapsed in 1991. Since the issue lies not in the US’s ability to retaliate but in its willingness to do so under specific conditions, the most practical approach is to adopt deterrence measures that North Korea perceives as credible.

First, Japan and South Korea should prioritize expanding their capabilities to neutralize North Korea’s nuclear missile launchers. A key advantage for the US, Japan, and South Korea—compared to NATO during the Cold War—is that North Korea is estimated to have around 50 nuclear warheads, far fewer than the tens of thousands in the Soviet arsenal.

In this context, Japan’s planned acquisition of enemy base strike capabilities should focus not only on expanding the number of available strike assets but also on improving their precision and destructive power to ensure maximum effectiveness against North Korean launch sites. At the same time, South Korea’s kill chain should further enhance its deep-strike capabilities by increasing assets like the Hyunmoo-4 missile, which is designed to penetrate deeply buried facilities.

Additionally, South Korea’s Drone Operations Command, established in 2023, should undergo a major expansion in drone assets capable of effectively detecting, tracking, and striking North Korean missile launchers. By integrating high-precision missiles and unmanned systems, both Japan and South Korea can significantly reduce North Korea’s ability to deliver nuclear strikes, thereby reinforcing deterrence.

Second, as Japan and South Korea expand their strike capabilities, Japan’s defense architecture should be aligned with South Korea’s Three-Axis System. This integration would allow both countries to allocate their finite military assets more effectively when targeting North Korea’s nuclear-related ground units. For example, given the geographic distance, Japan could focus on striking fixed targets such as command centers and underground missile storage sites while South Korea concentrates on eliminating mobile launchers that require rapid response and precision strikes.

Additionally, harmonizing Japan and South Korea’s missile defense structures would improve the likelihood of intercepting North Korean missiles. While Japan has developed its missile defense in close coordination with the United States, South Korea has opted to develop its own independent missile defense system, instead of fully integrating into the American-led ballistic missile defense framework.

However, aligning the two countries’ missile defense systems would significantly enhance regional interception capabilities. A fully integrated defense network would not only establish a more layered interception system against incoming North Korean missiles but also enable earlier response times—as Japan and South Korea deepen their real-time missile-tracking cooperation—South Korea’s response times could improve further. By improving both offensive and defensive coordination, Japan and South Korea can maximize deterrence and reduce North Korea’s nuclear strike effectiveness.

By implementing these measures, North Korea would be left with only a limited number of launchers capable of delivering nuclear weapons. While it is possible that some missiles could still be launched from the remaining launchers and a few might evade American missile defenses, North Korea would have to consider allocating few nuclear warheads against Japan, South Korea, and the United States. This would be necessary both to achieve its long-term political objectives and to deter US-ROK combined forces and US Forces Japan (USFJ) from retaliating in the short term.

Moreover, North Korean leadership would face significant uncertainty about whether its remaining nuclear missiles could successfully penetrate American missile defenses. In essence, by increasing their conventional strike capabilities and aligning their military strategies, Japan and South Korea could ensure that a substantial number of North Korean launchers are neutralized. This would force Pyongyang to operate with significantly reduced military options, making its attempt to create nuclear decoupling less credible.

However, this strategy is only viable as long as North Korea’s nuclear arsenal remains limited. If Pyongyang dramatically expands its warhead stockpile and launch platforms, conventional deterrence alone will no longer be sufficient, and the risk of nuclear decoupling will escalate beyond control. The US, Japan, and South Korea must act decisively—before the balance of power shifts irreversibly in North Korea’s favor. Time is running out.
