I agree, it's worrying how Trump's presidency may turn out for not only the conflict in the Middle East but for Ukraine and other states under oppression and war too. However, I think the only thing to do is to remain optimistic that some good may come, and then the US will hopefully not only pick better next time but have better candidates to choose from.
As for the Palestine-Israel situation, as I heard someone say recently, the "solution" is not two states, rather that should be the outcome of finding a solution to conflict and terror. That's what needs to be worked on first and foremost. And that means dealing with the Iranian Islamic regime unfortunately, and weakening it. It needs the world's attention on that over and above what is happening in Gaza and Lebanon. Just imagine how impactful it could be if all of those protesting in support of globalising the intifada and calling Sinwar and Nasrallah heroes would instead call the IRGC to account and raise awareness of the oppression happening there. It would change everything.
