Well, 40 years ago it attacked the Iraqi nuclear facility with the help of Iran and prevented Saddam from getting the bomb..
Well, the fighter jets and weapons system platform (a pair of Mark-84 unguided bombs fitted to each aircraft) they used in those airstrikes were made by aerospace companies in the United States (General Dynamics and McDonnel Douglas), so I think American companies did have a role to play, however indirectly.
There's no denying Israel wouldn't exist today (at least not the form it presently exists) if not for the timely and generous support and assistance (militarily, monetarily and in spirit) from the United States of America -- just an observation!
