As far as I can tell, it's just some meme being passed around amongst regressive left circles; and as is almost always the case, there is no evidence being presented to support such a notion. I first found out about it in an argument with my aunt, who said to "mark her words" (which is funny, because every time she's said that in the past, things never ended up panning out the way she insisted they would) that Trump just started a war with Russia, China, and North Korea; and when I pointed out how asinine that was, she just looked down her nose at me and insisted that I just hadn't done my research. Which in her mind probably amounts to little more than watching MSNBC, and accepting whatever drivel they spew as gospel.
