Interstate War

Interstate wars are armed conflict between two or more sovereign states. They may arise from disputes over territory, resources, ideology, or power and can escalate into large-scale regional or global confrontations.

Iran’s War With Israel and the United States

Type: Interstate War
Impact on U.S.: Critical
Status: Worsening

In February 2026, the United States and Israel attacked Iran, killing Supreme Leader Ali Khamenei and targeting nuclear and military infrastructure. A Pakistan-mediated ceasefire and June MOU halted large-scale fighting, but both sides have since traded strikes over alleged violations. A durable settlement remains elusive, with core disputes over Iran’s nuclear program, the Strait of Hormuz, and sanctions relief unresolved.

U.S. Confrontation With Venezuela

Type: Interstate WarPolitical Instability
Impact on U.S.: Significant
Status: Unchanging

Venezuela’s political and economic crisis stems from two decades of authoritarian mismanagement under Hugo Chávez and Nicolás Maduro, which produced an 80 percent collapse in GDP and drove nearly eight million Venezuelans abroad. U.S. special forces seized Maduro in January 2026, with acting president Delcy Rodríguez now governing under Washington’s pressure. Twin earthquakes struck near Caracas on June 24, 2026, killing over 5,500 people and deepening a humanitarian crisis the government is ill-equipped to manage.

Conflict Between India and Pakistan

Type: Interstate War
Impact on U.S.: Significant
Status: Unchanging

Nearly eight decades after the 1947 Partition ignited conflict over Kashmir, India and Pakistan fought their most serious military confrontation since 2019 after a militant attack killed twenty-six tourists in Indian-administered Kashmir in April 2025. A U.S.-brokered ceasefire has held since May, but India’s suspension of the Indus Waters Treaty has prompted Pakistan to warn that water coercion could have serious consequences for regional peace.

Violent Extremism in South Asia

Type: Interstate WarTerrorism
Impact on U.S.: Limited
Status: Unchanging

Relations between Pakistan and Afghanistan are strained by cross-border militancy, with Islamabad attributing a surge in deadly attacks to Tehrik-e-Taliban Pakistan (TTP) fighters operating from Afghan territory, an accusation the Taliban government denies. Pakistan has responded with strikes on Taliban military facilities, declaring “open war” in the most direct military confrontation between the two governments to date.

Conflict With Hezbollah in Lebanon

Type: Interstate WarTerrorism
Impact on U.S.: Significant
Status: Unchanging

Since October 2023, Hezbollah rocket attacks have displaced roughly 96,000 Israelis from northern Israel, triggering cross-border exchanges and a full Israeli ground invasion in March 2026. The offensive left Israel controlling roughly 20 percent of Lebanese territory and over one million Lebanese displaced. In June, a U.S.-brokered framework conditioned any Israeli withdrawal on Hezbollah’s disarmament—a condition the group has rejected, leaving Israeli forces entrenched in southern Lebanon.

North Korea Crisis

Type: Interstate War
Impact on U.S.: Critical
Status: Unchanging

Under leader Kim Jong-un, North Korea has pursued nuclear weapons and ballistic missiles to guarantee regime survival, posing an acute threat to South Korea and Japan—both key U.S. allies. Kim has deepened ties with Russia, providing artillery and troops for the war in Ukraine, while silencing domestic opposition through mass detention and political purges.

War in Ukraine

Type: Interstate War
Impact on U.S.: Significant
Status: Unchanging

Russia’s February 2022 full-scale invasion of Ukraine has killed over one million people and left Russia occupying roughly 20 percent of Ukrainian territory. Ukraine has countered with long-range drone strikes that have knocked out up to 40 percent of Russia’s refining capacity, while Russia continues to bombard Ukrainian cities. U.S.-mediated talks between Russia and Ukraine have yet to produce a ceasefire, and the two sides remain divided over territorial concessions and security guarantees for Ukraine.
