WASHINGTON - A prominent US Muslim civil rights and advocacy group Monday issued an open letter to President Barack Obama asking him to use his anticipated announcement of a troop build-up in Afghanistan to address allegations that US personnel abused Afghan detainees. The Washington-based Council on American-Islamic Relations (CAIR) also urged Obama to use his Tuesday address at the US Military Academy to speak out against the decision by Swiss voters to ban minarets, a move that is a violation of religious freedom and a breach of int'l law. In an open letter to President Obama, CAIR National Executive Director Nihad Awad said, As you prepare to address the nation on the conflict in Afghanistan, I urge you to seek peace and reconciliation, not escalation. When you took office, you clearly stated that torture and abuse of detainees would no longer be permitted. These new reports of prisoner abuse at a secret interrogation facility in Afghanistan sound eerily similar to those that so tarnished our nations image and interests in recent years. I ask you to address this important issue when you speak to the nation on Tuesday. I also urge you to use the opportunity presented by your prime-time address to repudiate the decision of Swiss voters to deny Muslims in that nation the same religious rights granted to citizens of other faiths. Our nations silence on this flagrant denial of religious freedom would send a very negative message throughout the Muslim world, which must improve its own record on religious rights. Any additional military personnel sent to Afghanistan will have little impact if the Afghan people see the United States violating human rights or offering even tacit support to the denial of religious freedoms.
