So the Russian ambassador to Turkey was just assassinated in Ankara, and Turkey is in NATO, which means other NATO members must come to its aid in the event of a shooting war, and the U.S. is ~a month from swearing in an unintelligent, uninformed, pro-Russian, ham-fisted asshat as president, so I’m pretty sure this is how WWIII starts.
Just for reference, this is eerily similar to how WWI started.
