Donald J. Trump said the other day that the missile strike on a Syrian air force airfield doesn’t mean we are “going into Syria.”

Hold on, Mr. President!

We already are in Syria, sir. President Barack Obama ordered several hundred special forces troops onto that battlefield to assist and train and coordinate attacks launched by “free Syrian” rebels fighting the Russian-backed government of dictator Bashar al Assad.

I also would add that the missiles launched from ships off the Syrian coast suggest that a more serious involvement by the United States in that conflict.

Times and circumstances do change, Mr. President, as you now are learning. Someone will need to remind the president that he used to believe that we should leave the fighting to the rebels. He also used to suggest that Assad’s forces — along with the Russians — could be capable of taking out the Islamic State terrorists.

Let the Russians deal with ISIS, he said. Sure thing, Mr. President. That will work out just fine.

My point, though, is that we already are engaged in Syria. Our special forces put their lives on the line every moment of every day they are deployed there.

The bigger, more important, question is whether we’re going to commit thousands of troops to fight ISIS head to head.

I’m now concerned that the president hasn’t given that option the careful, thoughtful and prayerful consideration it deserves.
