That's not strictly true. You're forgetting the 1947–1949 Palestine war, the first part of which was effectively a civil war where there's ample evidence of Jewish militias, with premeditation, taking part in land grabs every bit as much as the Arab militias.
In the West and especially in America this aspect is overlooked and even denied, as it doesn't fit the narrative of Israel as the underdog. Conversely, in the Muslim world this is pretty much the only aspect they want to discuss, for similarly self-serving reasons.
Israel fought back, and got territorial gains. Of course there were Jewish militias, Jews in British Mandate era were constantly being attacked by local arabs.
Anyway, even with all the complications of this era and our ability to form a tidy nerrative, the comparison of Israel to American and Chinese empirialism is just crazy talk. This stays true even if you totally accept the Arab narrative.
Did you see a map recently? Do you grasp the size of Israel vs it's neighbors? (The Sinai desert, which Israel gave back to Egypt as part of the peace agreement is x3 larger than Israel)
You can't clamp together imperialists like US Germany and China with Israel defense strategy, that's just weird.
Now don't get me wrong, some israeli leaders did/do crappy things, but never at the scale of China US or Germany, or for that matter any colonial country. It's a whole different scale.
