This article (link below) makes an absolutely crucial argument: the strike against Syria was UNCONSTITUTIONAL. The author, con law lawyer Garrett Epps, doesn't argue that the strike was immoral (maybe, maybe not; although I think not) or illegal under international law (almost certainly). No, without congressional authorization, even under the War Powers Act, the president cannot order an attack on a sovereign nation as he did here unless that nation has attacked us (it hasn't). Congress could authorize such an attack, but it routinely abrogates its constitutional duties. Most congressional representatives--Democrats and Republicans--don't want to take a stand. Any choice--because there is no "good" choice--will prove unpopular with some segment of voters. And for this, Paul Ryan and others will draw a fat pension.
Let's be clear about this. This isn't about Trump, it isn't about Republicans, it isn't even about Syria--it's about the U.S. Constitution and the blatant disregard of the Constitution.
This needs to stop.
