The only way out of this terrible mess is through a viable two-state solution (the UN supported the idea of a return to 1967 borders, Hamas have accepted this, but the US has always vetoed it, saying the borders need to be negotiated on Israel's terms.)
While the House and Senate is beholden to AIPAC and others (check how many House representatives are pro-Palestinian So, just how powerful is the Israel lobby in the US? | The Independent | The Independent 2013) and Biden needs votes for an election next year, that is never going to happen.
America supplies Israel with 3.3 billion's worth of arms every year (Five things you should know about U.S. weapons transfers to Israel | American Friends Service Committee (afsc.org) so the military struggle is hopelessly one-sided.
Filthy, disgusting things have been done on both sides, like they were in Northern Ireland.
The game was up for the IRA when 9/11 happened. The US, now a victim of terrorism, pronounced war on it. They clamped down on the money the IRA was sourcing from America and the IRA had to negotiate.
When governments are beholden to any vested interest / powerful lobbying groups, this shit happens.
