If you believe that then ask the fairies at the bottom of your garden
They have an enormous sea coast :-- so how is that blocked
They have a border with Egypt does Egypt block that ?
Naturally because of the constant suicide bombers from Palestine and the constant rocket attacks Israel have sealed their border
But Palestine was free to have a nice life when Israel withdrew from Gaze but they went straight to a war footing
So either you do not know what has happened there or you just want to blame others for the inability of the Palestinians to conduct a normal lifestyle
They have to import most of their stuff from Israel even their fruit and veg and the biggest employer was Israel
That will never come back, they are finished as a group
So your statements that they were in a concentration camp is simple hogwash
