His announcement threatened a renewal of U.S. military involvement in the country’s long sectarian war.
In a televised late-night statement from the White House, Obama said American military planes had already carried out airdrops of humanitarian aid to tens of thousands of Iraqi religious minorities surrounded by militants and desperately in need of food and water.
“Today, America is coming to help,” he declared.
The announcements reflected the deepest American engagement in Iraq since U.S. troops withdrew in late 2011 after nearly a decade of war. Obama, who made his remarks in a steady and somber tone, has staked much of his legacy as president on ending what he has called the “dumb war” in Iraq.
Obama said the humanitarian airdrops were made at the request of the Iraqi government. The supplies were delivered to the tens of thousands of Yazidis trapped on a mountain without food and water. The Yazidis, who follow an ancient religion with ties to Zoroastrianism, fled their homes after the Islamic State group issued an ultimatum to convert to Islam, pay a religious fine, flee their homes or face death.
Mindful of the public’s aversion to another lengthy war, Obama acknowledged that the prospect of a new round of U.S. military action would be a cause for concern among many Americans. He vowed anew not to put American combat troops back on the ground in Iraq and said there was no U.S. military solution to the crisis.
Even so, he outlined a rationale for airstrikes if the Islamic State militants advance on American troops in the northern city of Irbil and the U.S. consulate there in the Kurdish region of Iraq. The troops were sent to Iraq earlier this year as part of the White House response to the extremist group’s swift movement across the border with Syria and into Iraq.
“When the lives of American citizens are at risk, we will take action,” Obama said.
He said he had also authorized the use of targeted military strikes if necessary to help the Iraqi security forces protect civilians.
Obama spoke following a day of urgent discussions with his national security team. He addressed the nation only after the American military aircraft delivering food and water to the Iraqis had safely left the drop site in northern Iraq.
The Pentagon said the airdrops were performed by one C-17 and two C-130 cargo aircraft that together delivered a total of 72 bundles of food and water. They were escorted by two F/A-18 fighters.
The planes delivered 5,300 gallons of fresh drinking water and 8,000 pre-packaged meals and were over the drop area for less than 15 minutes at a low altitude.
The president cast the mission to assist the Yazidis as part of the American mandate to assist around the world when the U.S. has the unique capabilities to help avert a massacre.
Officials said the U.S. was prepared to undertake additional humanitarian airdrops if necessary, though they did not say how quickly those missions could occur.
Administration officials said they believe unilateral U.S. strikes would be consistent with international law in part because the Iraqi government has asked for Washington to take military action. They also said Obama had the constitutional authority to act on his own to protect American citizens.
Republican Sens. John McCain of Arizona and Lindsey Graham of South Carolina praised Obama’s proposed actions Thursday night but said much more will be necessary.
“This should include the provision of military and other assistance to our Kurdish, Iraqi, and Syrian partners” who are fighting the militants, airstrikes against the militants’ leaders and forces and support for Sunni Iraqis who seek to resist the extremists, they said.
