You're not wrong, but the question then becomes "why did the US send an advanced military defence system that needs a hundred highly trained American operatives to work".
I'm guessing the reason is a combination of politics (lots of American politicians with ties to Israel) and practical reasons (validate that these systems still work against the enemies of the state without actually getting involved in a war directly, perform analysis for future improvements for defence on home soil, get people behind Israeli lines to extract intelligence that might not be shared willingly).
I had a scale that kept measuring! It was great! I lost so much weight in the week before the battery finally gave out! Too bad my clothes didn't get any looser and all that weight came back on when I replaced the battery, but for a short moment in time weight loss became super easy! Turned out there was a reason other scales stopped measuring lol.
