I get slightly desperate realizing how people are lead to such naive discussions, even in a place with supposedly instructed, informed persons.
Maduro may be a dictator, a murderer, whatever. This has absolutely no relation with the reasons for US invading, bombing and killing Venezuelans, or whichever country. For about a century, US has been doing it all over the world, not because they wanna live in a better, peaceful world - quite the opposite, they've been doing it for supporting coups and stablishing dictatorships that favour their supremacy, their role as the most powerful country in the world.
Do you really, really believe Mr. Donald is very concerned about the lives of poor venezuelans? Or, just to stay in the region, he supports El Salvador dictator because he's a very nice fellow?
