Absolutely, and its not happenstance he's doing that at a ceremony for soldiers. I'm not sure he even consciously is aware of it (I think its just his nature), but he's priming people for connecting the two (soldiers and his enemies). This is exactly what tyrants do.
I'm somewhat hopeful in that I see more and more people finally seeing just how comprehensively despicable Republicans have become. It took Turmp openly brandishing and gloating about it, but people are really starting to see who are the ones doing almost all of the horrible shit in this country. We're gonna need more to if we don't want it to take lots of bloodshed to stop them.
