@gemlog I don't know if it's going to end in civil war, a revolution, or world war 3. It depends on how bad things get economically and who on the political spectrum it affects.
Trump is already starting to lose support within his own party. It's possible these actions regarding Venezuela violate the War Powers Resolution of 1973: https://en.wikipedia.org/wiki/War_Powers_Resolution
If there's a draft for a war, I think the other two are more likely because the last time there was a draft, it was the Vietnam War and everyone hated it. All conflicts (the US hasn't officially declared war on anyone since 1942) since then were done with enlisted personnel
