I agree that an attack on Syria by the US is generally bad.
But you may want to consider some interesting facts:
-The US gave notice to Russia before the attack. I can't imagine a situation in which the Russians, having received notice, would not have informed Syria. So, in effect, the US informed Syria before the attack.
-Despite having lobbed 59 Tomahawk missiles, the US did not destroy the runway. i would think that if 59 missiles were dispatched randomly, at least 1 would have cratered the runway, but no. So I can't help but to think that the runway was deliberately protected.
-Russia has deployed a airdefense system which was well within range of the missiles. Yet the Russians did not activate their defense.
-The Tomahawk missiles were slated to be decommissioned anyway.
-Finally, the "attack" was so inconsequential that airplanes are already taking off from the runway, a day after the attack.
It's hard to come to any other conclusion that the "attack" was no attack at all, but rather an orchestrated drama to fool the warmongers crying for the destruction of Syria. If Trump had done nothing, the din of warmongering would have become deafening. Now, they have been silenced. I think Trump has outsmarted the warmongers.
