WHITE HOUSE - “Iran appears to be standing down,” U.S. President Donald Trump said in an address to the nation the morning after more than a dozen ballistic missiles targeted two Iraqi air bases housing U.S. troops.

“No American or Iraqi lives were lost because of the precautions taken, the dispersal of forces and an early warning system that worked very well,” explained Trump, adding only minimal damage was sustained.

In a highly anticipated speech, Trump signaled the U.S. would not take military action in response to the attacks, but instead would impose additional harsh economic sanctions against Iran to further damage its economy.

Iran fired missiles into Iraq early Wednesday following threats by Iranian leaders of retaliation against the United States for an airstrike ordered by Trump that killed Iranian Quds Force commander Qassem Soleimani, who the U.S. leader said “was responsible for some of the absolutely worst atrocities.”

The president, in the White House Grand Foyer flanked by Vice President Mike Pence, Secretary of State Mike Pompeo, Defense Secretary Mark Esper and military leaders, said he would be asking NATO to become more involved in the Middle East, but he did not give details.

Trump also called for other signatories to the 2015 Joint Comprehensive Plan of Action to follow Washington’s lead and abandon the nuclear deal signed with Iran.

“The time has come for the United Kingdom, Germany, France, Russia and China to recognize this reality,” Trump said.

Michael Kugelman, deputy director and senior associate of the South Asia program at the Wilson Center, told VOA’s Urdu service that keeping in place the agreement that limited Iran’s nuclear activity in exchange for sanctions relief is of top importance to European allies.

“The European countries, which are really the ones that are in this nuclear deal, they have made it very clear throughout this crisis that they have no intentions of ending this nuclear deal with Iran,” Kugelman said. “They still see that as the safest bet to make it least likely for Iran to build nuclear weapons.”

While Trump condemned Iran for terrorism, vowed it would never be allowed to obtain nuclear weapons on his watch, and announced new economic sanctions on the country, his remarks were also uncharacteristically restrained about an adversary, especially hours after it targeted bases housing U.S. military personnel.

Trump offered an olive branch of sorts to Tehran, saying the two countries could cooperate on issues of mutual concern.

The Islamic State group “is a natural enemy of Iran,” Trump said. “The destruction of ISIS is good for Iran, and we should work together on this and other shared priorities.”

The U.S. president also offered words to the Iranian people, saying, “We want you to have a future, and a great future, one that you deserve. One of prosperity at home and harmony with the nations of the world. The United States is ready to embrace peace with all who seek it.”

Iran’s Supreme Leader Ayatollah Ali Khamenei called the Iranian strikes a “slap in the face” to the United States and said the “corrupt presence” of the U.S. in the region should come to an end.

Iranian President Hassan Rouhani added later in a tweet that Iran’s “final answer” to the killing of Soleimani “will be to kick all U.S. forces out of the region.”

The Iraqi prime minister’s office said there were no casualties among Iraqi forces, and that it had not received reports of any casualties from the U.S.-led coalition.

The statement said Iran notified Iraq that it was carrying out its response to the U.S. strike.

Iraq also rejected any violation of its sovereignty and aggression on its territory and called for restraint to prevent the U.S.-Iran crisis from developing into a devastating war.

Iranian Foreign Minister Mohammad Javad Zarif wrote in a tweet after the missile strikes that Iran had taken and concluded “proportionate measures in self-defense.”

“We do not seek escalation or war, but will defend ourselves against any aggression,” Zarif said.

Iran took & concluded proportionate measures in self-defense under Article 51 of UN Charter targeting base from which cowardly armed attack against our citizens & senior officials were launched.

We do not seek escalation or war, but will defend ourselves against any aggression.

The chairman of the Senate’s foreign relations committee, James Risch, said he hopes “the Iranian regime has learned a lesson.”

The Republican senator said Trump clearly explained the policies his administration has been pursuing against Iran’s “unacceptable conduct on all fronts.”
