I have to wonder if there wasn’t a tacit agreement between the White House and the Kremlin on what would happen here. From what I’ve read the missile strikes didn’t crater the runway, which is usually the goal of this kind of operation. If that’s true can see a realpolitik agreement here: sure, make yourself look like a big-boy President, and as long as you don’t completely wreck the Chinless Wonder’s airfield we won’t use our air defense system against your missiles.
The outcome we have now is elevated chest-beating and posturing, with the U.S. and its awful Arab allies on one side and Russia and its awful Arab and Iranian allies on the other.
