Let’s be real about why this shit is happening. “Right to exist” is a convenient catch phrase, but the real reason is that the US Military needs allies and resources in the region to secure commodities like oil and minerals... and opium, in the case of Afghanistan. Oh, and also to prevent these smaller countries from thriving with assistance from rival superpowers. We could argue about the utility or the morality of these policies, but it’s all pointless if we don’t begin with a realistic understanding of the actual conditions.
Israeli “democracy” is about as legitimate as US democracy, which is to say it’s a total scam operated by ruling class interests. Recent elections show this pretty clearly. Many of the non-Jewish US politicians and right wingers who love Israel so much are actually anti-Semitic as fuck. If you personally are a Zionist for personal/religious reasons, that’s a different conversation. Geopolitics don’t care about that. It’s about cash, resources, power, etc.
