US needs to do some soul-searching

The Boston Marathon bombings that killed three people, including 23-year-old Lu Lingzi, a Chinese graduate student at Boston University, and left more than 260 injured, were a senseless attack of terrorism to say the least.

The wounded suspect, 19-year-old Dzhokhar Tsarnaev, told interrogators this week that he and his 26-year-old brother Tamerlan, who was killed in a subsequent police encounter, were motivated by radical Islamic views and anger over the US-led wars in Iraq and Afghanistan.

Though Tsarnaev claimed that he and his brother were self-radicalized and did not belong to any organization, investigations by FBI and the inquisitive media have continued, spreading all the way to Russia's Dagestan, from where the brothers migrated to the US 10 years ago.
