Israel lacks enough land, population, or oil to be a major player on the international stage if it stood on its own. Even Ba'athist Iraq or Saudi Arabia could hardly be considered “global powers.” And what would greater Israel even expand to? The revisionist Zionist groups aren’t advocating for settlement of Jordan anymore. You have the Sinai, southern Lebanon maybe, and more parts of Syria. Israel lacks the military capacity or political will to take Jordan or Iraq.
Israel was born out of Western imperial interests. Its existence has always been for the purpose of having a Western-backed state in the Middle East. It’s hard to imagine a scenario where it’d be in either the US or Israel’s interest to no longer associate with each other (geopolitically speaking at least)
And you always won’t really be able to get around the population problem. Even if Israel was as successfully Zionist as it possibly could be, the global Jewish population is a sixth as large as Turkey’s. Sure Israel has a significant Arab population and so do occupied (or occupyable) territories but an expansionist Israel would be reliant on keeping those populations repressed. Their own military would be more preoccupied with preventing uprisings than projecting power
