The Saudis deal with terrorists very quickly and those terrorists DON'T repeat their crime.
Osama bin Laden was tossed out of Saudi Arabia even though his family was wealthy and important. The KSA had no time for his brand of terrorism.
He had to go to other countries and bribe himself into their country.
Every Friday morning the Saudis mete out justice in their local town squares. All are invited.
We COULD have witnessed a head-chopping but...we declined. The guy had murdered.
No one else is to blame but the people who commit those horrific crimes/sins. There is no such thing as "the devil made me do it." We all do indeed have free will.
If someone is threatened by terrorism against his family, then that poor soul is really between a rock and a hard place.
That position doesn't USUALLY come out of the blue. There are always warning signs.
Mohammed himself was a terrorist, brigand, and desert pirate. Everyone who aspires to him and his religion is transformed into his likeness...;-(
