There's a major downside to this that won't be long in coming. I don't know what, but I do know the same gang in the Intelligence Community who have been after Trump's scalp since he was sworn in wouldn't have been so sure that he had to strike Syria if they didn't know this was going to have a major downside.
You mean a downside like “Whoops, sorry Mr. President, we gave you the wrong intelligence, kinda like the yellow cake fiasco back when, I guess that gives you a good reason to drain the intelligence swamp.”
