Israel does not need an excuse. Israel wants to avoid war at all costs, because throughout the years of trading land for peace, they are now surrounded by enemies that are pointing somewhere between 150 to 200,000 missiles at them, many of which contain chemical and biological warheads. All of their cities are in range, even from Iran. How can anyone possibly imagine they want to start something at this time?
Because the majority in Israel have not forgotten the run up to WW2 and the false hope they had that America and isolationist Europe would come to their aid.
Thank God Israel places no trust in the ability of American politicians to accomplish anything..Israel like the rest of the world has learned to use our weaknesses to accomplish their goals.
