Hamas does not want to coexist with Israel. It’s that simple. This is from Mossab’s Wikipedia page. He was also an undercover spy for Israel. God bless this incredible man:
Mosab Hassan Yousef (Arabic: مصعب حسن يوسف) (born 1978) is a Palestinian and son of a Hamas founder and leader SheikhHassan Yousef. From 1997 to 2007, he worked undercover for Israel’s internal security service Shin Bet, which considered him its most valuable source within the Hamas leadership.
According to Israeli sources, the information Yousef supplied prevented dozens of suicide attacks and assassinations of Israelis, exposed numerous Hamas cells, and assisted Israel in hunting down many militants, including his own father. In March 2010, he published his autobiography titled Son of Hamas.
