Numerous innovations (like the bandage that saved Gabriel Giffords' life), numerous American companies doing R&D in Israel (Intel is fabricating their upcoming Sandy Bridge line in Israel), and of course, military relations (weapons/defense technology, American weapons caches in Israel, intelligence cooperation, stuxnet).
So they have some R&D there. Lots of countries do that, and our relationship with them isn't quite the same. Lots of tech in Ireland for example, but we weren't getting in their mini-religious war quite so much in the 90's and protecting one side like that.
As I outlined above and which you are purposely and blatantly ignoring, our relationship is more than economic.
Ireland doesn't face an existential threat from anti-Western regimes, nor does it have the same military relationship that we do with Israel. The situations could not be more different.
