I do not suggest isolationism. I do suggest being prudent with American money and military entanglements. Israel has been a bad investment for Americans. Our unqualified support of them has caused us mostly problems in the world.
Israel gets an Dome, national healthcare, and protection at the expense of tax paying Americans while the American government, which is highly influenced by AIPAC and other lobby groups, tells Americans to pound sand for the same benefits and to get back to the office.
While I do not wish ill on them or the Palestinians, neither Palestine or Israel are worth an American life or an American tax dollar. They are not truly American allies or an American problem. The idea Israel "must be supported" or you are an anti-semite Jew hater as Ben Shapiro stated, is beyond arrogance.
