The OP states that the Israeli government has not learned from its past mistakes, but the OP does not tell us what he/she has learned from the Israeli government’s past mistakes. The OP does not state what Israel should now do to protect its citizens and its interests.
Here is what I have learned:(a) The world does not strenuously object to Arabs’ lobbing rockets into Israel if Israel retaliates and kills more Arabs than the Jews killed by the Arab-lobbed rockets. (b) The US, regardless of which party controls the White House, publicly scolds Israel but continues to support the Jewish state. (c) The Arabs have been attacking Israel with lobbed rockets or similar attacks for the last 64 years, and Israel is, relative to the Arabs of the region, flourishing.
concerned.1 writes in part: “Hashem gave us Eretz Yisroel and we have got to protect it.” I agree with the first clause, but where in Torah are we commanded to protect Eretz Yisroel. I thought Hashem agreed to do that for us. We have not lived in Eretz Yisroel for major portions of out history. Should we not conclude that when we are again worthy of residing in EY, Hashem will take us there and protect us?
