So true. And yes, when the Muslims have been given territory that was once controlled by Israel, including its roads, houses, buildings, electrical and plumbing infrastructure, and agricultural fields.......within a few months the place looks like a ghetto. Think Detroit.
I saw that when Gaza was turned over to them. IIRC, some liberal Jews in the U.S. bought a thriving nursery there from their Landsmen and gave it to the Palis "as a gesture of good will". Within days, if not hours, the place was dismantled as the locals stripped the place of everything of value.
The Muslims believe everything is a zero-sum game - no one improves himself until he can advance at the other guys expense.
