Pretty much depends on whether it is in benefit of his own career as politician, I think he will try to stop the war in Ukraine but he probably won't do anything to try to save guard the rights of the people from Palestine, he will do whatever Israel tells him it is necessary to protect their territory from Hamas, Hezbollah and Iran.
By the way, it has been already revealed there was an actual plot going on from Iran to try to assassinate Trump, so that should give you an idea on how much Tehran does not want Trump to mess around and give unchecked support to Israel.
Trump is likely to push Ukraine into accepting to give up some land to Russia, pretty much in Zelensky dismay.
I agree with you on this, I believe that as soon as he takes office he will seek to end the war in Ukraine and Russia immediately after. I also believe that he will push Ukraine to accept losses in this war instead of negotiating with Russia because that is much more difficult. Recently, President Zelenskyy also reacted negatively in an interview with Radio Ukraine. He said even the United States could not force them to sit down and listen at the negotiating table, which could indicate that Trump had set conditions that were not what he expected.
Regarding the war in the Middle East, I think he will not seek to stop it and will continue to support Israel because America's interests in the Middle East largely depend on Israel. But things may not get any worse as some reports say Trump will try to negotiate with Tehran before moving forward with plans to impose tough sanctions.
