National Pot Dec 14 A17 - Family blames Britain for son's radicalization

The heading is all that is necessary to understand the article. Unfortunately it's thesis leads quickly to extremism. Surely it is not Britain but some part of Islam that is responsible for the son's Islamization. Blaming anything other than Islam for problems is all too common. However, if the family is right, and Britain is to blame, it means that Britain is not able to prevent the radicalization of Muslims living in the country and is therefore a threat to other countries. Should the U.S. attack it to wipe out the threat as it did in Afghanistan? Alternatively should Britain close its borders to Muslims or expell those that are already there, (as all Jews were expelled from the Arab countries in 1948) because they are incapable of controlling the development and implementation of Islamism? As repugnant as these suggestions are, they are the logical extension of blaming Britain for the Islamization of a Swedish Muslim family's son.
