There are four options for American voters: vote red, vote blue, vote third party, or don't vote at all.
Voting red is just bad. I highly doubt that the Gaza situation would get any better if Trump gets in, but I know for a fact that a lot of things will get much worse.
Voting third party is a wasted effort. Sure, every sane person would prefer different people to run America, but the the shit fptp system means they'll never get any traction. In another election voting third party could be worth it, since a third party might slowly get more support, but not this one.
Not voting is just pointless. That's just choosing to not impact anything.
That only leaves voting blue. It's not great, but it's the only option left.
