Since the disintegration of the Soviet Union, the world followed the course laid out by the United States. The crumbling foundations of arms control and disarmament regimes, Russian invasion of Ukraine, the aggressive economic and diplomatic rise of China, and new multilateral arrangements by emerging states are all contributing factors to an ongoing reshaping of the global power dynamic that is challenging American leadership.

The uncertainty created by global institutions that are not effectively coping with Russian aggression, Chinese expansionism, and American retreat is exacerbating the threat of nuclear weapons use. This uncertainly is also causing some states to wonder if they need to pursue their own safety—in the form of nuclear proliferation. After all, the open threat of nuclear weapons use is occurring for the first time in the lives of many national leaders.

In the bipolar world that existed at the time, rivals were kept from attacking each other by competing in small technological battles over nuclear delivery vehicles, not the destructive power of their weapons. But, with the withdrawal of the Cold War era’s arms control arrangements, the threat of arms racing increased as the United States took a clear lead in conventional warfighting technology.

The ever-increasing distrust among rivals, coupled with the weakening of international institutions, is a central cause for the erosion of trust in the current world order. The perception of declining American power and interest in maintaining global order fuels a sense of self-reliance in the security realm, particularly for emerging powers. Careful not to criticize the United States publicly, Japan and South Korea, for example, wonder how reliable American extended nuclear deterrence remains in the wake of Chinese and Russian aggression that seems unchecked.

Closer to home, North Korea is already an established nuclear power and a looming threat that requires a robust defensive mechanism. A fear of extinction is ever present because reliance on a third party for security is always a risky endeavor.

On the other hand, active conflicts in the Middle East cannot be ignored. This is particularly true when a known nuclear state and an aspiring nuclear state are rivals and engaged in a shooting war.

Iran is known to have enriched uranium to at least 60 percent, and may soon, or perhaps already has, enriched uranium to weapons grade. Fortunately, Israel seems willing to rely on its conventional capabilities to win against Iran. This is a positive outcome in the midst of active conflict.

Repeated attempts to halt the Iranian nuclear program by the United States and Israel are proving insufficient. Wisely, Iran is abstaining from fielding a nuclear weapon, but this decision could change in the near future.

Efforts to prevent Iran from building nuclear weapons with the “Iran Nuclear Deal” (commonly known as the Joint Comprehensive Plan of Action (JCPOA)) were never supported by the left or right in the United States. Thus, President Trump ended the deal during his first term. American withdrawal from the Intermediate-Range Nuclear Forces (INF) Treaty in 2019, due to Russian cheating; cessation of talks on New START since 2021; American withdrawal from the Open Skies Treaty (OST) in 2020, due to Russian cheating; and the unresolved deadlock on the proposed Fissile Material Cut-off Treaty (FMCT) leave advocates of arms control unhappy.

The sense of mistrust that pervades also prevents confidence-building measures from playing any role. Emerging powers are also questioning the concept of a nuclear umbrella in the wake of President Trump’s clear desire to force Europe to bare a much greater share of their own security. Ukraine, the victim of Russian aggression, once inherited Soviet nuclear weapons, which they gave back in 1994 in return for security assurances—only to see Russia violate those guarantees at little expense.

At this current juncture, stability is hard to maintain. Erosion of trust in the United States is evident. Weakening and non-existent nonproliferation regimes are of great concern. States that once rested easy in American security guarantees are now thinking differently when it comes to their own survivability, security, and territorial integrity.

Ineffective international institutions have also become a driving factor in undermining the global narrative surrounding the validity international policing in crises. In such circumstances, states with potential capabilities are now looking to themselves more than ever before. Whether the world is headed for a period of anarchy or a new hegemon is uncertain. What is certain is that everyone will feel the results.

In this still frequently neglected or covered-up existential rivalry, the two sides face equally monumental but decidedly asymmetrical consequences. Should Beijing lose, the CCP will likely fall and fade. The Chinese nation, people, and state, even with the same name, will survive and likely thrive. Should Washington lose, however, not only will the American system of government likely fail, but the American way of life and national independence will diminish as American power and influence is superseded by a domineering PRC.

After long delays, hesitations, and self-delusions, a rare American consensus emerged to focus on the epic PRC-USA competition and fending off China’s effort to spread illiberal Chinese power. Given its vast well of resources, extensive network of alliances, great pool of talent, still functional democratic decision-making mechanism, and vibrant marketplace of ideas, the United States is coming up with cost-effective measures to win this competition, likely cheaper and more peaceful than what was required during the Cold War.

Critically, the United States should aim to achieve three hierarchical objectives in the PRC-USA race. They are ranked in descending order of importance. First, prevent the CCP from reordering the world by taking over global leadership. Second, prepare for but deter an all-out war with the PRC. Third, work toward a sociopolitical and ideological transformation of the PRC into a constructive peer. In the end, the US must ensure that Beijing is unwilling and/or unable to replace American leadership in the world.

The United States and its allies should curb the idealistic but toxic enthusiasm for globalization and world governance. The evolving ideals of the right to intervene (RTI) in other sovereign countries for the responsibility to protect (RTP) other country’s citizens, for example, should remain an inspiring ideal rather than a legal norm. Extremely rare and absolutely necessary cases of RTI and RTP are acceptable.

Americans must unapologetically strengthen the United States by maintaining dominance in economics, military power, education, and innovation. It must also remain a nation that is admired for its freedoms at home. It is in the greater interest of the world (including the Chinese people) to put America First, make America strong, rebuild America back better, and let America lead again. These campaign slogans were not only useful for presidential campaigns in 2016, 2020, and 2024, but they are important in reminding the rest of the world what is in their own best interest—a strong America.

These ideas should be delinked from the shortsightedness of isolationism and disassociated from any particular politician. The US must succeed in the international competition for power. It must also use its immense power judiciously to be ever more cost-effective.

A quick look at Taiwan may be a good illustration. Taiwan is critical for Beijing and the primary point of contention in the PRC-USA rivalry. The ROC (Republic of China) was a major US ally after World War II. However, the ROC’s international status was literally traded away by the United States over 40 years ago. The desire to enlist the PRC in the fight to win the Cold War against the Soviet Union proved more important.

Taiwan subsequently evolved to become the first democratic Chinese polity of and, in many ways, a leader across Asia. It has also drifted away from the monolithic Chinese world, to seek its own self-rule, autonomy, and independence.

The CCP, for its own political interest rather than the Chinese national interest, desires to absorb Taiwan with bribery, tricks, intimidation and force. Should Beijing accomplish that goal, it would achieve a major objective of its “great power” strategy, making a giant leap to dominate the Asia-Pacific and score a significant victory over the US and its allies.

The United States must not let Taiwan fall to Beijing. This is not because of the island’s beauty (its old name Formosa means beautiful island in Portuguese). Nor is it because of the advanced microchips that Taiwan makes. It is because the United States cannot allow the CCP to win the PRC-USA rivalry. American interests and the interests of a free world dictate that the US must ensure Beijing does not take Taiwan over the will of the Taiwanese people.

Without fundamental sociopolitical reform at home, even peaceful unification of Taiwan and the PRC should be objectionable to the United States. It sends the wrong signal to every nation watching the outcome of this competition. Winning the PRC-USA rivalry is much more important than the Beijing-Taipei dispute.

The United States must use its power well in defending Taiwan against the PRC. Between peaceful unification of the island with the Chinese Mainland in a framework of democratic federation on the one end, and Sino-American military conflict in response to an invasion of an independent Taiwan on the other end, there are many options. The US can employ numerous and inexpensive options like destroying the “Great Firewall of China,” providing smart weapons to Taiwan, fighting at the time and place of American choosing, and altering the nuclear balance in East Asia. The list can go on.

Imagination, wisdom, persistence, and perseverance, more than mere force and material power, will enable the United States to safeguard world order. The Taiwanese people are counting on an American victory in the PRC-USA rivalry.
