Egypt and Jordan have both normalized relations with Israel. They are absolutely not threats.
Syria and Lebanon are failed states. The threats to Israel come from non state actors within them. Such actors can only be truly neutralized by (a) capturing and trying the leadership -rather than making them martyrs by extra judicial killings, and (b) by removing their legitimacy, i.e., by ending Israel's illegal occupation and colonization of the West Bank, and by letting Gaza breathe. Basically, these non state actors can only be defeated politically at this point.
That said, it is clear that Israel has gone rabid. The rest of the world at this point is more worried about the safety of its neighbours from it. There is no credible actual threat to Israel any more. But there is a credible genocide and ethnic cleansing going on under/by Israeli arms. The Israeli far right (that is part of the government) contains powerful elements that are already planning the colonization of Gaza and Southern Lebanon. Internally, even dissenting Jewish Israelis are facing repercussions for not towing the extreme nationalist line. The settlers are the strongest political force in the country. Etc etc. Israel needs to be deradicalized. There need to be limits placed and there need to be consequences
Ultimately we need nothing less than the complete and blind application of international law. If that is too radical for Americans or Israelis, too bad.
That sounds like a reasonable comparison, until one realizes that we are not talking about WMDs here, we are talking about the occupied Palestinian territories. Then, your comparison not only falls apart, but is also exposed as a bad faith one.
First, if Israel giving up the territories is similar to Ukraine giving up its WMDs, i.e., an existential threat, then Israel should never do that. I.e., peace is impossible and the two state solution is impossible. The only option left is ... ethnic cleansing and genocide. Is that what you are arguing for?? Be clear about what you say. Because I don't think you are arguing for the dismantling of the apartheid regime in all of greater Israel: one state from the river to the sea with equal rights for everyone.
Second, Israel actually has WMDs and would be keeping them after the establishment of a Palestinian state. So, if anything it would be in a stronger position than Ukraine, heaving the guarantee from its neighbours and its own WMDs to fall back to.
Third, you are comparing Israel to Ukraine. This casts Israel as the victim, the one that is subjected to occupation and violation of its integrity. The opposite is true. Israel is the occupier, the oppressor and the violator international law.
So, no, your comment doesn't stand to scrutiny.
