Maybe, but you are missing a point too. Even if it was a mistake to create Israel in hindsight (the world was very different just after 1945), the fact is that there are millions of people who live there, call the place home and will do anything to keep what they have.
Good luck “making them disappear” by basing all your reasoning on dismissing them as zionists and a settler state who cannot possibly feel like they truly belong there.
The best you can get is a palestinian state and expulsion of settlers from the West Bank, but for that you need assurances that Iran or anyone else won’t be placing missiles 20km away from any major Israeli city, which anyone who thinks like you will never be able to guarantee, because of what you believe.
Now compare that to russia, largest country on Earth, with infinite resources, enough nukes to destroy every major capital, huge strategic depth (less than the US, more than most countries) acting like they are the victim against a country that committed the crime of not submitting to their influence and then annexing 5 Israels’ worth of their land.
Syria was WW3’s Spanish civil war.
