While Trump condemned Iran’s action, he did not call for a military response, saying instead, “The United States is ready to embrace peace with all who seek it.
The escalation of military actions between the two countries comes days after a drone strike that killed Maj. Gen. Qassem Soleimani, one of Iran’s top military figures. The killing of Soleimani, according to the U.S., came after intelligence sources said Soleimani was planning to attack Americans or U.S. interests in Iraq.
Iran said Soleimani’s killing was an assassination.
Soleimani’s death and Iran’s attack on the two bases are the latest chapter of a complex history between the two countries, peppered more with conflict than cooperation.
From a CIA-led overthrow of the country’s prime minister in the 1950s to the taking of American hostages to the withdrawal from a nuclear deal, here’s a look at how we got to the point in the relationship between the United States and Iran.
What happened most recently that led to Wednesday’s missile strikes by Iran:
On Dec. 27, a U.S. contractor was killed and two U.S. servicemen were injured in a rocket attack against a military base in Kirkuk, Iraq.
The United States claimed the attack was carried out by an Iranian-backed militia called Kataib Hezbollah, a militia that Soleimani dealt with as a proxy for Iran.
On Dec. 29, Trump ordered a missile strike against Kataib Hezbollah forces in Iraq and Syrian territory. The strike killed at least 25 militia fighters.
On Dec. 31, Kataib Hezbollah breached the gates of the U.S. Embassy in Baghdad. They demanded U.S. forces leave the country.
After receiving intelligence reports that Soleimani, leader of Iran’s Revolutionary Guard Corps’ elite Quds Force, was planning an attack on Americans, Trump on Friday ordered a drone strike at the Baghdad airport, targeting Soleimani and killing him.
Vowing “severe revenge,” Iran launched ballistic missiles Tuesday on two U.S. bases in Iraq. No Americans were injured in the attacks.
On Wednesday morning at the White House, Trump announced more severe economic sanctions against Iran but did not threaten military retaliation.
