there is no way that western powers can identify, much less control the radical factions of islam.
only other islamists, those who are “peace loving” can know which ones are destructive and can control.
it is simple: tell all islam we will no longer tolerate these radical elements and will destroy anyone or anything that harbors terror.
the west contains the weapons that can destroy islam. let them police themselves or face the peril of noncompliance.
Self policing has been completely non-effective. islam as a religion has failed to do what every other major religion on the planet has done over time: go through reformation and renounce violence as a means of conversion.
Forced conversions happen today in the middle east, africa, and parts of asia-pacific such as Indonesia on a daily basis. Islam persecutes Christians, Jews, Buddhists and any other religion that does not ascribe to islamic "values."
Self policing has failed, time for islam to deal with the consequences of its actions. Those who remain "silent" out of fear of repraisal from their fellow muslims are as guilty as those who commit the acts of terrorism IMO.
