Jesus your still laughable.
Isreali is a tiny nation surrounded by enemies. Enemies who want them all dead.
Of course they build fences and maintain control. Common sense 101.
If you lived in Isreal you'd be applauding the Isreali's Govt for doing so.
Oh and they gave up the land in a try for peace. They had to forcibly remove many of the Jews living there. It was not a popular decision among many Isreali's.
Do you know enough to understand Gaza is not part of Israel?
Gaza is occupied by Israel.
Israel can not claim self defense against those it occupies.
If Jews want peace (they don't) they would end the occupations of Gaza and the West Bank.
But then Israel would no longer exist as a Jewish state between the River and the sea.
Jew and Arab would live as equals in the Holy Land.
Some Jews will die first.
