See, this is going to be a problem whatever happens.
You have elected officials refusing to control the situation in their cities. Purposefully refusing. They are standing down the police force, or if not that, just not deploying them.
Trump is rather hobbled on how far he can go, before going too far. He's there for the all or nothing approach.
It's up to the states and the states are purposefully and politically refusing to stop this or in the case of some, making it outright worse, See ; NY/OR.
So, Trump left to the bunker - seen as cowardice from some, but I don't think people appreciate that he's the President.
I also think people underestimate how much the paid terrorists, Antifa are after him and WOULD over throw him/kill him given the chance. There was a credible threat to his life and the SS knew that.
So, he goes away to his bunker, but he emerged in the morning with a stern message and a game plan. He declares Antifa domestic terrorists and says that if states can't handle their shit - he will.
The "Too Far" approach.
You may be against using the military on your own shores, but if Trump refuses to do anything, you'll be saying someone should do something.
You're at the "Too Far" approach now. Forced, may I add by Democrats because they know exactly what kind of message it sends. The message of Trump "using the military on its own citizens" is a leftist wet dream. It's something they have created purposefully.
He's caught between a rock and a hard place. Go there and you cannot go back. Don't go there and there will not be anywhere to go from.
So what is it you propose he do? Let chaos reign so that there is no America tomorrow? Or go "too far" and pull the pin, so to speak?
I'm sorry, but you're actually in a situation that is at that point and I don't think you're ready to accept that. This is a civil war with the far left, terrorists from the far left and black people too stupid to appreciate what they're actually doing.
Trump will dither on it, perhaps he'll wait it out to pull the pin for a few days, because it really is the last resort and it will get mildly worse before it gets better. As well, it's election year and there's people like you who feel divided and are too shocked to see the full gravity of the situation.
You elect Biden though and the "powers" you mention being used briefly on looters et all, will instead be instituted into policy by the dishonest, corrupt people who have egged on these very protests.
Trump has a terrible choice on his hands, but inaction isn't really an option now. I really don't know what you expect him to do.
