I already know you'll say that stuff is not military tech but whatever, our alliance with them is a good deal and this article will explain more to you.

You know, that's a pretty vague article. It mentions missile tech, which I'd also already mentioned, although I believe it's more of an information transfer rather than production units or designs. UAVs is a good one, Israel does indeed do a good line in unmanned military vehicles, more so than many other states who can afford the military manpower instead. It's something that the US is getting into more heavily, although the US has also been experimenting in this area since at least the 60's if I recall.
Random "technology" seems a bit of a reach, there are many states that are making significant technological progress. Israel perhaps splits their technology budget more towards the military than some, but without specifics it seems hard to create an informed opinion on the potential benefits. Frankly, the article is pretty short on actual information and pretty long on propaganda. The entire thing can largely be summed up by "the alliance with Israel is good for the US, have some buzzwords".
If you've got actual specific advantages that you'd like to discuss I'd be very interested. It has recently become relevant to my interests to be informed about military technologies and their impact on the US and it's allies. I don't pretend to be highly knowledgeable, but I've learned a bit and I'm keen to learn more. However at the same time I'm not real eager to simply accept generalist assertions at face value when we could just as easily talk about the specific benefits that such an alliance provides.
We are not the military super power we are because we live in a bubble, we've always used resources around the world to make and keep us the war machine we are. Why would we stop doing that now?
You wouldn't, but using external resources is done with consideration and forethought. The US does not use or rely on foreign military resources just because, it's a considered choice. You'll notice that the US has not bought the Eurofighter Typhoon or the Dassault Rafale, because of considered choices that they have made.
If you're going to make the argument that Israel is part of the US policy of adopting foreign military technology, I expect you to be able to provide at least some reasoning for that statement. For example, the Spike is a remarkable piece of man portable and light vehicle mountable missile technology, however the US has chosen not to field it in favour of it's own equivalent hardware. What is it specifically that Israel is providing the US?
