In his own words - the dismissal of the deportation case against Mosab Hassan Yousef

Mosab Hassan Yousef, author of Son of Hamas, was subject to deportation hearings in the US, ironically, for his connection to Hamas.

Yousef, disillusioned by Hamas' murderous methods and fanatical ideology that was focused on the destruction of Israel, became, at the risk of his life an informant for the Israeli intelligence service, Shim Bet.
