Well, there would be generally less tensions with many other countries acting in an expansionist manner than with Israel doing so.

Given the history short (modern) history of Israel and the religious animosity of the neighbors etc. it would be certain to inflame more hostility internationally than Rawanda taking a piece of Burndi for instance. But I'm sure you are already aware of all this. I went back and read your previous posts. It seems you may be looking for an anti-Semite under every rock. Well... next rock. I'm just pointing out practical reality. I don't have an axe to grind with Israel existing.
