We have seen in the Boston bombings case how terrorists depend on a network of sympathizers. But the Russian connection remains a mystery. The press should follow up on the Russian angle to the Islamic terrorist bombers story before President Obama gets carried away with cooperating with Russian President Vladimir Putin. The assumption by the media that the former KGB officer is genuinely interested in helping the U.S. solve its Islamic terrorism problem should be subjected to scrutiny. After all, al-Qaeda leader Ayman al-Zawahiri has been identified by KGB defectors as a Russian agent. Former PLO chief Yasser Arafat and the international terrorist Carlos the Jackal, who converted to Islam and is in prison in France, were also identified as KGB agents. Putin doesn’t have clean hands in this dirty business.
