I'll say right now the U.S. has done everything possible for Israel (in the current situation) and we still are. As for whether Israel could have done more ... yes. Will they do more...? Why not.
Now, I wonder if Israel still has civilians in bomb shelters in the north or whether they have relocated all further south...
The US has not done everything possible for Israel. Far from it. Once again, people refuse to recognize that our party's leaders can make a bad call.
