Trump is a real-estate guy. When Trump sees the beautiful Gaza strip, he sees a Mediterranean Riviera, full of hotels, entertainment, and casinos. Trump sees Gaza as a Mediterranean Las Vegas.
When a Muslim looks at Gaza, they see a way to bilk world charities by deliberately oppressing their own people and forcing them to live in poverty and squalor. Hamas looks at Gaza as their Kingdom where they are free to rape and murder their own slave-subjects while building tunnels and weapons to murder Jews and anyone else who they believe opposes them and their archaic bloodthirsty-caveman version of Islam.
If Gaza were to be cleared of the primitive barbaric murdering 7th century Islamists, and if it was run by normal civilized Western people, Gaza would be one of the wealthiest regions on Earth.
