It pretty much has run off and on since the end of WWII, when Israel became a recognized country.
Nobody did that, and the Gaza Strip is not part of Israel.
Egypt and israel=]
There is no war between Gaza and Israel.
It was made by the armistice between Egypt and Israel in 1949.
There are three questions here that have each been answered separately. See the Related Questions below.
The usual in Israel; Judaism trying to survive, and Islam complaining when Israel doesn't feed the Gaza Strip (they were firing rockets into Israel from the Gaza Strip).
No.
Northern and central Israel are on the Med. Southern Israel is separated from the Mediterranean Sea by the Gaza Strip.
No. According to the Oslo Accords in 1993, the Gaza Strip officially belongs to the Palestinian Authority. It is currently occupied by the Hamas Paramilitary/Terrorist Group.
Ironically, the Gaza Strip is the only territory in the entirety of the former Mandate of Palestine (Israel and the Palestinian Territories) that is not actually contested between the Israeli and Palestinian governments. Israel ceded significant control of the Gaza Strip to the Palestinian Authority in 1993 and subsequently gave it full control in 2005.The reason that there have been numerous wars in the Gaza Strip is because the Hamas government that currently rules over the Gaza Strip has a policy that peace with Israel is impossible and continues to lash out against Israel. If the Gaza Strip was more willing to behave peacefully with its neighbors (both Egypt and Israel), there would be fewer conflicts in the Gaza Strip. (Even Palestinians are getting tired of Hamas as can be seen in the parody of the "Thank You Hamas" videos.)
No, it has been blockaded by Israel.
The Gaza Strip is an anomaly. It was part of Egypt, but when Egypt and Israel signed a peace treaty, Egypt refused to take back the Gaza Strip. Under international law, it was considered part of Israel, but Israel does not believe in occupying other areas, so they declined to take over the Gaza Strip. It is not part of any country, nor is it independent.
