I will keep this short, since PDF is not conducive to a calm discussion of Israel. This topic comes up every other month here, and the answer is always the same.
You are entirely right, your opponents are wrong.
We have veto power over their defense industries and foreign policy (and even, to some degree, their domestic policy, e.g. house building regulations). No American soldier has ever been sent to fight for Israel, and none ever will, unlike with our other allies. They anchor our interests in the region, often doing work that we cannot (help Jordan when it was invaded by Syria, bomb Osirak, bomb the Syrian reactor, etc.). Those are the "hard interests," the soft interests include intertwined economies, joint R&D, and shared Western values.
If we could pay our deadbeat NATO allies to defend themselves, it would be a bargain compared to the raw deal we have today (we pay instead of them, plus our troops are at risk), and our relationship with Israel is far more advantageous than our relationship with, say, the Philippines, who dislike us and kicked us out, but whom we are bound by treaty to defend. We have many "mutual defense" treaties, but does anyone seriously believe that Taiwan, Japan, Germany, etc. even has the capability to help the US if it is attacked in North America, let alone the will? At least with Israel, the responsibilities and expectations are symmetrical.
Israel serves our interests very well in the hierarchy of the alliance, it is one of the last allies I would look to eliminate.
