Team Assad made the mistake of using gas to kill people when he was supposed to use conventional explosives.
He could wiped out 50 people with a barrel bomb and it wouldn't even be news worthy in the US. We don't approve of any deaths unless its followed by massive destruction. You can't youtube a chemical weapons attack. It's boring. We want splosions.
Let that be a warning to any country on Israels sh*tlist. Make your civil wars splodey or else we are going to launch stuff from our flying robot force.
Hell, the US could have wiped out 50 people in a drone strike and it might not even make the news here. We'd issue an "They were all ISIS'ish and Assad must step down. and Iran. Iran did this because they are destabilizing the region. So this is all Iran's fault that we killed one guy with a rifle and 49 people who happened to look like the type of people who may carry a rifle. (Followed by FoxNews editorial that makes claim that Iran is killing dozens of Syrians and maybe gearing up for a nuclear strike on Israel...home of the Jesus trilogy" statement provided to us by AIPAC. They do give out awesome t-shirts for every 15 press releases so that's a bonus.
Russia can carpet bomb an entire block and no one would give a shit. They'd do their standard "Was the terrorist who did that. We weren't even there that day. Probably the US backed forces that dropped those Soviet era dumb bombs from TU-22 flying at about 30,000 feet. subscribe to our youtube channel to watch our glorious modern Airforce from the 90's drop dumb bombs on the terrorists (in other part of country)"
10 people show signs of chemical burns and the US starts preparing to send in the Jem' Hadar.
