MojNews-U.S. Senator Lindsey Graham said retaliation "is not necessary," for now, after Iranian missiles hit Iraqi military bases hosting American troops.

His remarks came hours after he called Iran's strikes "an act of war."

"In my view, retaliation for the sake of retaliation is not necessary at this time," Graham tweeted Wednesday. "What is necessary is to lay out our strategic objectives regarding Iran in a simple and firm fashion."

Iran recently attached a US base in Iraq by its missiles. The Pentagon confirmed missiles were launched from Iran and targeted at least two Iraqi military bases hosting U.S. military and coalition personnel at Al-Asad and Erbil on Tuesday.
