Countries should have banned Muslims from entering their countries a looooooong time ago - like maybe this Muslim bomber's parents.  He was born and raised in England but his Muslim roots stayed on and 22 years later he emerged as another Muslim terrorist.  If England paid proper recognition of the hatred Muslims have for the Western world, those 22 people would not have been murdered.

There is something to say about allowing foreigners to immigrate into established countries.  But its way too late.
