WTF are you talking about?
It's a non-analogous analogy:
* Assad - the wife-beater;
* The beaten wife = the gassed men, women, and children;
* The guy who sees the beating, doesn't call the police, and does nothing meaningful = Trump.
A few obvious analogy-nullifying differences:
--> Unless "Tommy_Carcetti" stupidly regards the UN as the world's police, there are no "police" for Trump to call. And

"Tommy_Carcetti" really is

that stupid,

calling the UN would do worse than nothing.

Just ask Rwandans and West Africans about what UN
Blue Helmets do and don't do!
--> Unlike the observer who did nothing meaningful, Trump's attack crippled the airfield that delivered the gas attack, in a way that illustrated the precision of the US military, and illustrated the kind of knowledge the US has. Assad is probably rotating his living quarters among several of Syria's deepest bunkers.
-->
Obama watched Assad slaughter 10s or 100s of thousands of Syrians, and other than
letting Assad dupe him into thinking the surplus chemical weapons Assad "surrendered" were Assad's entire chemical weapons arsenal,
didn't do a whole lot.
