Look, I know that immigration is a contentious issue, but sanctioning a country for not repatriating its citizens is a disproportionate response. Trump and Co. are really obsessed with immigration to even do this. It says a lot what values they have.
Trump is going all in. He's reverting to the 19th century way of strong arming other countries over petty things. He's reviving the old-school capitalist imperialism.
Are those people really Columbian citizens? I would not put it past Trump to just command ICE to land the next plane full of "somehow latin looking people" somewhere south of the border.
I suppose, but we're talking about international diplomacy. And a modern one at that.
Trump's strong arming sounds so 19th century though. His open threat of taking Panama canal, Canada, Greenland, and renaming the Gulf of Mexico is so manifest destiny.
