There would be some short-term economic consquences, of course, but if we all co-operated, pulled together, and remain resolute, we will endure, and the long-term economic impact could be very positive.
I am not Jewish, but do not think Israel should give up one inch of land. If anything, they should take enough more to protect themselves totally and completely, and they should throw out of the land they take every single "palestinian", innocent or terrorist.
I also think we should send back to their country of origin, any visitor or immigrant from Arab lands who do not immediately condemn the abhorrent behavior of Iran, Iraq, Saudi Arabia, Lebanon, Syria, etc, etc,etc.
And, no more food, medicine, aid, or trade with any of these countries, period, until they "get a clue" about minding thier own business.
My reason for being so angry? They are behaving, collectively, like Hitler and the Third Reich. There is no point in appeasing them, and to continue to do so will only make WW3 all the more inevitable.
