They are not trying to wipe out any countries, only murderous scum who think nothing of planting bombs on buses or in cafe`s and wiping out athletes in Munich. They cleaned up Lebanon and could have kept it, but withdrew back to the Golan heights. They have not got an army for occupying countries.
Rockets were being fired from Gaza constantly, it was only the Israeli shield that kept most of their population safe, when the rockets stopped they had a ceasefire. Simple solution, dont prod a bees nest.
