Disarming Hamas, as we have seen, is a very dangerous business and no other country but Israel will put its solders at risk to get it done, so if Trump's International Stabilization Force is tasked with doing that job, no country will join it. If Hamas does not volunteer to disarm, I cannot think of any scenario in which Trump's peace plan turns out well.
Some wars just have to be won before peace can be negotiated, and this is one of them.
