Those who have been doubly hurt by the Boston bombing and the recent arrest of the two alleged Canadian terrorists on Monday, are the vast majority of hard-working, law-abiding Muslim Canadians.

It's said that a majority of Muslims have been hijacked by a tiny percentage of Islamic extremists. But it's also true that many Muslims consider the incidents of September 11, 2001, to have been staged by the Bush administration, the CIA, Jews, etc. The question arises as to why a majority of Muslims would assume that nothing bad could be delivered by Muslims? And why have many Muslims related all bad things to the United States, other western countries and Israel? Majority Muslims in the West should open their eyes and minds and get beyond the conspiracy theories.
After decades of mistaken policy with the Middle East, the U.S. should do what's necessary to prevent Iran from becoming a nuclear power, and get rid of Assad and his sycophancy to Tehran.
