US-Iran Confrontation and Geopolitical Tensions: Military Operations

The conflict began on January 3, 2020, when a U.S. air strike in Baghdad killed Iranian Major General Qassem Soleimani. Iran responded with missile attacks against U.S. facilities in Iraq on January 8. Tensions escalated significantly in June 2025 when Israel launched strikes on Iranian nuclear and military sites, prompting Iranian missile retaliation. The U.S. provided bunker-busting bombs to Israel for strikes on Iranian infrastructure, including Fordow, Isfahan, and Natanz. Following these strikes, Iran launched missiles at Israel and attacked U.S. bases in Qatar and Iraq. President Trump announced a phased-in ceasefire, but Iran struck the Al Udeid Air Base in Qatar on June 24, leading Trump to criticize the U.S. response as weak. In early 2026, U.S.-Israeli strikes killed Iran's supreme leader, Ayatollah Ali Khamenei, on March 1. Iran retaliated with drone attacks on a U.S. embassy in Riyadh, an Omani port, and a U.S. base in Bahrain. A ceasefire reached in April broke when Iran launched missile and drone attacks on the UAE's Fujairah Oil Industry Zone; Iran denied targeting the UAE, blaming U.S. 'adventurism,' while reports emerged that Saudi Arabia and the UAE had conducted secret bombing raids on Iran in April. By late May, Iran destroyed over $1 billion in U.S. MQ-9 Reaper drones. The U.S. conducted 'self-defense' strikes in southern Iran on May 26, which Iran accused of breaching a ceasefire. The IRGC then struck a U.S. base in Kuwait, and on May 30, Iran shot down a U.S. F-15E fighter jet using a Chinese-made missile. Diplomatic efforts faltered in June 2026. Israeli strikes in Lebanon led Iran's negotiator to declare peace talks futile on June 14. On June 16, Trump announced a framework agreement offering Iran $300 billion and sanctions relief in exchange for abandoning nuclear pursuits, though the agreement reportedly excluded Lebanon from reconstruction funds. However, Israeli strikes continued in Lebanon through late June, prompting Hezbollah to warn of retaliation. Hostilities resumed on June 27 when the U.S. targeted Iranian missile depots, prompting the IRGC to strike U.S. deployment sites. By July 8, the U.S. responded to Iranian attacks on Bahrain and Kuwait with 90 airstrikes. Following the collapse of a ceasefire in mid-July, the U.S. conducted consecutive nights of strikes against Iranian infrastructure, which Iran met by targeting U.S. bases in Jordan, Bahrain, Kuwait, and Qatar. In late August 2026, Iran launched missile and drone attacks against U.S. intelligence facilities in Saudi Arabia and Iraq. The U.S. responded with strikes on Larak Island on August 30. On September 1, the U.S. launched strikes in the Strait of Hormuz following reports of IRGC attempts to mine the waterway and attacks on commercial shipping. Iran responded with missile and drone attacks against U.S. bases in Jordan, Bahrain, and Iraq. On September 2, U.S. missile strikes in Khuzestan and Kermanshah killed multiple personnel and civilians. In the Sirik district, U.S. strikes targeted residential areas and wedding ceremonies, which Iran characterized as war crimes. Following these strikes, President Trump declared a renewed U.S. campaign against Iran. Iran retaliated with coordinated attacks against U.S. installations in Kuwait, the UAE, and Iraq, and an attack on an Israeli air base. By mid-September 2026, the U.S. implemented a 'Tanker for Tanker' policy, striking three Iranian oil tankers on September 5. The U.S. cited Iranian missile attacks on American warships as justification. The IRGC retaliated by striking three oil tankers in the Strait of Hormuz and three U.S. vessels on September 6. The U.S. struck five more Iranian tankers near Kharg Island on September 8. Currently, the U.S. continues to apply military and economic pressure, while Iran maintains a stance of strategic resilience amidst ongoing military posturing.
