There is only one nation on Earth that is not an enemy of Israel, and that is the US. And the US will not, and should not volunteer for this mission. It would simply be a target, as it was before.
It appears that Israel may have more than just one country that would defend it against terrorism. Members of the European Union and/or NATO would fit that role, with the US leading the way diplomatically, it may work.
There is a solution with the help nations who are against facism and terrorism acting together. Moslem nations are not reliable and the United Nations is ineffective and treacherous. Israel cannot fight this battle alone, all peace loving and courageous people need to join in.
I believe that it will happen.
Target we will be, (as we already are.) But who else can do the job? In fact, before the present war started, NPR ran an interview with a pro-Palestinian group working to raise money, expertise, whatever in the US for Palestine-to-be. One thing they wanted was US soldiers on the border, boots on the ground, to protect Palestine from Israel. Interesting.
