As IRIS has extensively documented, the Palestinian "demographic bomb," the fundmental belief behind Israel's wrong-headed policies, is a myth.
Here is the best article on the topic. Today brings further news of the accelerating trend of Palestinians fleeing local Arab gunmen:
Fallout of Hamas' Rule Spurs Palestinian Desire to Flee
A growing number of Palestinians are openly saying they'd like to leave the West Bank and Gaza if given the chance, yet another indication of the deepening despair since Hamas was elected to run the government. Birzeit University pollster Nader Said, who has monitored emigration attitudes for 12 years, says the percentage of Palestinians willing to relocate once hovered just below 20%. That figure jumped to 32% in a September survey, surging to 44% among Palestinians in their 20s and 30s, and beyond 50% among young men.
This reaction is quite obvious to observers not blinded by leftist ideology to the following two points:
The violence of the Palestinian regime is fundamentally directed at Arabs, which makes them want to flee
Palestinians are not culturally distinct in any way that prevents their immediate assimilation into any other more attractive Arab environment
