Gaza/Israel?

"Military sources say that there is no magic formula to use to deal with ships that try to enter Israel's waters forcibly." Can Israel please tell us whether Gaza is part of its territory or not? It keeps changing its mind depending on what's politically expedient at any given moment. When defending Israel's barbaric treatment of the people of Gaza they say they've "left" the place and it has nothing to do with them; but when someone wants to go their to help them they're violating Israel's territory. So which is it?
