Remember that Trump’s real purpose in continuously needling and threatening to annex Canada, Greenland, and Panama is so he’ll have something to regurgitate whenever he needs a distraction and wants the media to focus on something other than one of his many damaging scandals or authoritarian power grabs, or just when he feels the media isn’t focused on him and he feels a need to be the center of attention again.
Can Trump deport suspected undocumented migrants without due process? “No. It’s not complicated. Anyone that tries to inject nuance into this simple question is not to be taken seriously.” Except he’s doing just that.
Can Trump completely ignore the rulings of the court system up to and including the Supreme Court? “No. It’s not complicated. Anyone that tries to inject nuance into this simple question is not to be taken seriously.” Except he’s doing just that.
Can Trump target specific people, companies, or organizations with punitive executive orders unless they bend to his will or do his bidding? “No. It’s not complicated. Anyone that tries to inject nuance into this simple question is not to be taken seriously.” Except he’s doing just that.
Can Trump withhold federal funding from universities and other organizations that don’t adopt Trump-friendly policies and give him direct control over their operations? “No. It’s not complicated. Anyone that tries to inject nuance into this simple question is not to be taken seriously.” Except he’s doing just that.
Can Trump threaten executive, legislative, or otherwise punitive action against news organizations and reporters who report on him unfavorably? “No. It’s not complicated. Anyone that tries to inject nuance into this simple question is not to be taken seriously.” Except he’s doing just that.
Can Trump unilaterally implement and rescind tariffs unilaterally, based on nothing but his personal whims? “No. It’s not complicated. Anyone that tries to inject nuance into this simple question is not to be taken seriously.” Except he’s doing just that.
I could go on and on, but I’m sure you get the idea by now.
Asking “can” he do something is irrelevant. The actual questions to ask are if there is anybody with the power and authority to stop him, do they have the ability to enforce it, and are they willing to use that power? If the answer to those questions are “no”, then the answer to whether or not Trump “can” do something is “He can, and he will, because fuck you that’s why.”
If there is nobody willing or able to enforce the law, those laws are mere suggestions that can be ignored when inconvenient.
