What is your threshold for often?

When was the last time a country with a functioning military was overthrown by outside intervention?

I guess we can count Iraq, though that requires connecting the First Gulf War and the Second, since the First Gulf War is when the Iraqi military was last seriously functioning.

The best way to punish them is to give Isreali left wingers and “out” which allows them a path back to normalcy so they can take political power and condition that with punishment of high ranking war criminals and a two state solution. But this cant really happen due to the current US admin.

I think you overestimate the appetite of the Israeli left-wing for normalcy, a serious two-state solution, or punishing war criminals. Like I said, at best, you'll get a handful of offenders from internal politiking. But the chance of there being some punishment for any significant percentage of the very large number of very active and intentional orchestrators of this genocide is... small. Zionism is unlikely to be meaningfully repulsed by anything but time, and that's assuming a best-case-scenario that the problem doesn't intensify.

People will fight to the death if they’re backed into a corner but they will throw a few people under the bus if given a path out.

Again, I consider that covered under my "Slobodan Milošević" scenario. Don't get me wrong, seeing Bibi die in a prison cell would be based and hilarious. But even that would only be a drop of water in the ocean of blood.

But if by Zionists you mean anyone who wants isreal to exists then you are backing isrealis in to corner and guaranteeing the conflict continue to be played out.

By Zionists, I presumed it was meant those who see Israel's existence as an explicitly Jewish apartheid state as core to its continuation. And as long as Israel remains Zionist in that sense, this shit will keep happening. Ethnostates are notoriously amiable to the whole lebensraum idea, regardless of whether it's currently-occupied territory they're looking at, or potentially occupied territory - or both.
