WASHINGTON (AFP) - US President-elect Barack Obama has vowed no retreat from his campaign promise to begin pulling troops out of Iraq and switch the military focus to Afghanistan. Obama told the CBS programme "60 Minutes" that "as soon as I take office, I will call in the Joint Chiefs of Staff, my national security apparatus, and we will start executing a plan that draws down our troops." "Particularly in light of the problems that we're having in Afghanistan, which has continued to worsen. We've got to shore up those efforts," he said. Obama said that from his inauguration on January 20, "it is a top priority for us to stamp out Al-Qaeda once and for all" and that killing or capturing the group's mastermind Osama bin Laden was "critical" to US security. Obama pledged to tackle controversial offshoots of Bush's "war on terror" - the US military's internment camp at Guantanamo Bay, Cuba, and harsh interrogations of captured terror suspects. "I have said repeatedly that I intend to close Guantanamo, and I will follow through on that," the president-elect said. "I have said repeatedly that America doesn't torture. And I'm going to make sure that we don't torture. Those are part and parcel of an effort to regain America's moral stature in the world," Obama added. But he did not elaborate on where the Guantanamo prisoners would be taken, whether they would be transferred to civilian custody in the United States itself, put on trial, or released. A command to redeploy troops out of Iraq or shut down Guantanamo could be done in short order under Obama's presidential prerogatives, and he is expected to reverse a slew of other contentious "executive orders" signed by Bush.
