Gaza is a cramped combination slum and jail, where people have been confined for their entire lives to suffer poverty, deprivation and hopelessness. They have Israel to blame for this: these people were driven out of their homes by the Israeli Army in 1947 and left to rot in something quite like concentration camps for over 50 years. They have no nationality, they have no jobs, no prospects, nothing. They are not allowed to enter the West Bank, they have no seaport, no airport, no sewer system, electrical power is intermittent.
Why would they NOT want Israel to just "go away" and let them move back into their homes? Very few Gaza Palestinians actually fought the Israelis, as they had no organization or weapons. When armies can to "defend" their rights, they were chased away, and the Israelis prevented them from going home again.
There is a reason why they voted for Hamas. At the time of the elections, the two major parties were Fatah, a corrupt WB organization, and Hamas, affiliated with the mosque and therefore seen as more honest. Hamas candidates were younger, as are Gazans.
Keep in mind that Hamas rules Gaza because of Condi Rice's poor intelligence, perhaps fed to her by the Israelis, who actually WANT Gaza and the WB to be divided, because two weak enemies are better than one stronger one. Condi thought democracy would bring peace and tranquility and unification. She was wrong, wrong, wrong.
If you were a Gazan, what would YOU do?
