Because the world in 1925 said no to chemical weapons. Obama drew a line in sand and ignored, Trump criticized and said he and all civilized countries would not ignore. He is following throug with that commitment now, just as he did last year. Russians already blinked and pulled their Navy out of harms way.

Holy crap, we actually have 3 or 4 FReepers who "get it". Great, succinct explanation, BTW!

Eh, I should restate that last:
To defuse this, what if Assad points the finger at & executes some “rogue general” (assuming we have no intel actually tying Assad directly to the gas attack)?
