There is always a way to escalate from the current point. For example they could ramp up the military production even more to the point that they are allowing israel to basically invade any country they choose.
They could also help strategically collect everyone they deem as " Hamas" and store them in camps to gas them in masses. They aren’t even close to holocaust level genocide yet.
This also ignores what would happen to minority groups inside of the us which could be executed for being trans etc. see laws passed in some states for “punishing predators” which often include trans people, this could very well escalate to giving the death sentence to minority groups.
The republicans have announced that they will be doing a genocide against the minorities in the US in the project 2025 plan. I think one genocide is already enough, although they should definitely stop sending munitions for the genocide ongoing in israel. I am not willing to throw more people under the bus just to show one party that I don’t support what they are doing. There is a time and place for that kind of criticism but it is not closely before an upcoming election which decides if the US would become a country led by a dictator
