CHICAGO (Online) - A group of Pakistani-Americans and anti-war activists delivered a letter Thursday to the Chicago office of Sen Barack Obama, calling him to cool political rhetoric about bombing targets in Pakistan. "We are particularly concerned with your public pronouncements earlier this week in support of violating the borders of our ally, the country of Pakistan. You must understand the sweeping dismay that your avowed support for US military incursions into Pakistan has elicited among untold numbers of Pakistani-Americans and peace activists across the country," the letter stated according to The Chicago Tribune. During his debate Tuesday with Sen John McCain, Obama said he was not calling for the invasion of Pakistan. But Obama added, "If Pakistan is unable or unwilling to hunt down Osama bin Laden and take him out, then we should." Ifti Nasim, host of a Pakistani radio show in Chicago called "Sargam," said the US was "making a mistake" by "attacking Pakistan and making Pakistan your enemy." He and other protesters criticised US military incursions into Pakistan's tribal areas in the northwest part of the country to attack Taliban and al-Qaeda targets. They also decried the Bush administration's use of unmanned military drone aircraft, which have resulted in civilian deaths. Nasim said McCain wants to continue the policy. The group plans to send a similar letter to the Arizona senator. Pakistani-Americans and other immigrant and anti-war groups such as the Chicago coalition against war and racism are planning an anti-war march at 2 pm Saturday at Devon Avenue and Leavitt Street.
