Jews want a regieme change in Iran, that's it, because the current regieme interferes with their greater Israel project and helps proxies fight against those goals, elsewhere.
But these jews don't care about beating Iran. That's not their goal. If they can get Americans to invade, it won't matter if the Americans win or lose. Iran would be forced to focus on the invasion, potentially shorting aid to proxies, and ending the direct threat to Israel, itself.
The last American invasion lasted a decade. We didn't win, Iraq is fractured into 3 parts, but Israel gained ground. One of those 3 parts is now helping in the effort for regieme change in Iran.
For Israel, its not about beating Iran. It's about ending the threat posed to Israeli expansion. If Iran becomes a fractured failed state, like Iraq, that's a win for Israel.
