Terrorism is neither an Arab nor a Muslim phenomenon. It has plagued this world of ours for thousands of years. It exists and thrives everywhere, in Europe, Asia, Africa, the Middle East, South America as well as North America. Neither the US nor is Boston unfamiliar with terrorism. In the 1850s John Brown, a radical abolitionist attempted to free slaves by a series of terrorist attacks “to force the nation into new political patterns by creating terror”. He was caught and executed for treason in 1859. His death helped indirectly to bring on the Civil War.
