It just keeps getting worse... So what if a lot of Israel's air defense is not made by them? Most countries in the world can't make their own, so those aren't countries to you? By the way, your argument crafted to criticize US imperialism actually justifies it, invading Iraq is okay since the US can make its own stuff and Iraq can't, also it would be okay for israel to attack their neighbors so long as they only use weapons they made themselves. And about the US aid, removing it would certainly be bad for Israel but they'd still be far from defenseless, their military budget is about 27 billion usd yearly (before the war), US aid is 3 ~ 4 billion a year, most US weapons are actually bought or developed jointly between the two countries, not given, and Israel has a massive military industrial complex itself.
