Iran's Gen. Qassem Soleimani would have been devastated to learn his surviving colleagues at the top of Iran's government considered the firing of 20 missiles at U.S. bases a "proportionate response" to his assassination.
Whether Tehran's military response is truly complete, of course, remains uncertain — although Iranian Foreign Minister Javad Zarif was unusually clear in tweeting shortly afterwards that the strikes "concluded a proportionate response."
Even if it is, the question is whether U.S. President Donald Trump will go through with his own Twitter threats to unleash overwhelming U.S. strikes — including against cultural sites — in retaliation. The lack of U.S. casualties, together with the president's own tweet following the strikes that "all is well," suggest that will not happen.
