You are not there and you don't know. (1) Nothing has shaken Israel's belief in defensive capability. 10,000 IDF were at the Litani in 24 hours ... IDF is over 500,000 if it needs. It was political incompetance, nothing to do with IDF (2) Israel is being attacked by NGOs and the UN, so we must attack back, not appease (3) Declining importance of Israel for US Jews ? Try declining Jewishness for non-orthodox Americans. Torah, Kalal and Eretz are the cornerstones of Juadism. If you don't have one, you are not Jewish. That is why a secular Jew, who has no Torah, is as at fault as a Naturei Karta, who has no Kalal or Eretz.
