So sure was Israel in its southern security that intelligence reports were downplayed; the military even redeployed troops from Gaza prior to the October 7. The brutality of the attack and horror at the hostage crisis left Israel so shocked that it delayed a ground invasion for 20 days.

Despite the delay, calls for ceasefire and accusations of genocide existed before Israel’s offensive began. All the same, every first-semester international relations student knew what would happen next: with Hamas no longer deterred, Israel’s only recourse was compellence.

Compellence theory is simply acting on the threat that keeps your adversary deterred. Israel needed to compel Hamas to surrender the hostages, disarm, and realize that attacking Israel is a bad idea—restoring deterrence. For nearly two years since, Israel has tested compellence theory; at best, with mixed results, not only with Hamas, but across the region.

The Lebanese terror group Hezbollah launched its own attack on October 8, 2023, which by the end saw the launch of approximately 10,000–15,000 rockets and 2,500 drone attacks that displaced at least 70,000 Israelis and killed 75 soldiers and 45 civilians. Israel’s effort to restore deterrence devastated Hezbollah, killing 2,500–3,000 fighters, eliminating the majority of its leadership, through an exploding beeper attack in advance of a ground invasion. Seeing their losses, the group agreed to partially disarm and stay out of further hostilities, being effectively compelled.

In Yemen, the Houthis likewise joined the attack on Israel with rocket and drone attacks, as well as targeting ships off its coast, causing significant supply-chain disruptions. The attacks prompted the United States (US) to designate them a terrorist group and launch an aerial campaign alongside the United Kingdom—on top of Israel’s responses.

The Houthis endured severe damage to its offensive infrastructure and lost hundreds of fighters but still managed to occasionally launch limited attacks. The Houthis are more weakened than compelled.

Iran, the financier of Hamas, Hezbollah, and the Houthis, for the first time acted against Israel directly. Retaliating against Israeli strikes, Iran launched ballistic missile and drone salvos against Israel in April and October of 2024. The tit-for-tat came to a head over 12 days in June 2025, as the two exchanged strikes while Israel tried to destroy Iran’s nuclear weapons program.

Though the damage Iran’s nuclear capability took is debated, what is known is Israel’s air superiority destroyed nearly all of Iran’s defense framework and eliminated several senior military staff.

Israel endured significant damage as Iran managed to breach its defenses on a few occasions, and the two have since agreed to a ceasefire, while simultaneously pledging readiness to attack in the future. So perhaps, they are mutually deterred for now.

Syria recently entered a new phase of its civil war following the downfall of Assad, an Israeli push to expand its buffer region, and the emergence of the Hayat Tahrir al-Sham (HTS) faction. HTS is led by Abu Mohammed al-Julani, an Islamic State affiliate who recently began targeting members of Syria’s minority populations, largely the Druze.

Israel intervened to protect the Druze, striking HTS sites until Julani quickly agreed to withdraw his troops from the Druze-populated areas. Prior to that intervention, there were rumors of Syria joining the Abraham Accords. While compellence worked to protect the Druze in the short term, it may have derailed a long-term peace deal.

Hamas remains the outlier. Ceasefire talks are again looking to collapse. The message is that despite the devastation, loss of leadership, approximately 17,000 lost fighters, and thousands of civilians killed in the crossfire, it can endure more. Israel’s attempt at compellence was so intense, that it sparked worldwide protests and allegations of genocide. Yet, rather than agree to Israel’s terms, Hamas continues to hold out, giving a statement that they will continue to fight until a Palestinian state is established.

The US attempted to broker multiple ceasefires, with some success in November 2023 and January 2025, but a deal to end the conflict remains elusive. If the US wants real results, compellence should target Hamas’ hosts and financiers, Turkey and Qatar.

While publicly on good terms with the US, the argument that Turkey and Qatar are state sponsors of terrorism would not be difficult to make given the support and protection they have offered Hamas. President Trump could threaten to add Turkey and Qatar to the list of state sponsors of terror unless Hamas agrees to Israel’s terms of ending the war.

There are indications that this could work. At least publicly, the two countries recently joined with Saudi Arabia and Egypt in a call on Hamas to disarm and relinquish control of Gaza to the Palestinian Authority. This is a good first step, but the call has no “or else”–type clause that would actually pressure Hamas.

With that support gone, Hamas’ political leadership’s only choice would be deportation from its hosts which would likely jeopardize their finances and potentially put them within Mossad’s reach or accede to Israel’s conditions. Ever self-interested, the hope is they would be compelled to the latter. This type of diplomatic pressure directed at Hamas’ sponsors could trickle down to Hamas’ leadership and potentially be the last best hope for Gazan civilians as Israeli Prime Minister Benjamin Netanyahu signals plans for a renewed military offensive in the enclave.

Whether deterrence is restored by Israel is yet to be determined. For the sake of civilians on both sides, let us hope it is restored and soon.
