Israels support of Hamas is a pretty good starting point. That one pretty clearly shows, how the Israeli government continues that situation.
The other one is looking at the situation from an Israeli perspective. Iran is the most open anti Israel country right now. A lot of other countries in the region, do not like Iran either and are somewhat willing to work together with Israel. That is Saudi Arabia for example. The issue is that the situation in Palestine is preventing that alliance from forming. So a deal with the Palestinians gives Israel greater security in the region as well. If done right that would only mean the northern border to Lebanon and Syria is challenged.
A lot of people seem to forget, what countries can take. Seriously WW2 was most everybody being willing to be bombed, have way higher casulties at the front, while rationing at home. That was true for everybody. Right now Russia has spend its war chest on the war, which means few cuts in pensions, education, infrastructure and so forth. A lot of money went to soldiers and workers in the arms industry. Millions of Russians got a better life due to the war. What we see right now is the war chest running low and that forces Russia to make cuts. So the question is how deep can Putin cut, before the systems collapses.
But Russia has a lot of natural resources and a fairly sufficent economy, while being able to trade with China. It is not perfect, but that can last a long time. Also Russia can just print Rubel. It hurts the economy long term, but Putin does not care.
