A peaceful resolution of the Ukraine war IS impossible. There is only one way to get a ceasefire: to give Putin what he wants. And that is no option for the Ukrainians. And for everybody else in the region. So once more Trump is talking BS. He will end no war, not there nor in the middle east. He seems to operate without any understanding of the reality. All the factions involved in those conflicts have their own agenda, Israel and Iran have, and Putin as well.
Putin cannot make a agreement in which he compromises. If he does, he is done. Politically dead, and may be physically, too. He has sacrificed 100k Russians in this failed "special operation" so far, he can't just say " Oh well, lets go home then."
And in Iran the situation is similar, admitting weakness is no option for the Mullahs. And Israel does what they believe is neccessary to keep their country, what ever it takes. They dont give a moist fart what Trump says or even what the UN says - we have seen this before.
