But by all means go to war over a guy that is an enemy of your own country because of some principle that even you don't believe.
Just don't expect people who are not hyped up on LSD to think you are anything but insane.
Who said ANYTHING about going to WAR? Yeah. WaPo should screen their employees more carefully. Maybe the CIA and FBI should investigate WaPo’s hiring practices...no, wait. They hire lots of former intelligence operatives, too.
But a journalist working for an American paper on a story should be safe from being murdered and dismembered when he enters his own country’s embassy. That’s a pretty good principle.
So you impose sanctions of some sort or another. There’s a lot that can be done short of war, especially since the US no longer needs Saudi oil. So how about imposing tariffs on petrolium-based imports from KSA, including crude, plastic, and sweet crude. Trump would like that. You can still do the big arms deal with them, and you punished them for murdering a journalist, IF KSA was the one who actually did it. End of story. No war.
