US Republicans' potential presidential candidate Jon Huntsman suggested a faster withdrawal of troops from Afghanistan than the one planned by President Barack Obama. Jon Huntsman, ex-governor of Utah and Obama's former envoy to China, believes that the targeted timeline for troop drawdown from Afghanistan, which starts in June and ends by the end of 2014, is not fast enough because of dwindling public support and financial cost of the war. President Obama has planned to start bringing troops back home next month when he still has to announce the size of the troops who would be the first to leave Afghanistan. In an interview with CNN, Jon Huntsman asked: "When you look at Afghanistan, can we hang out until 2014 and beyond?". Then he replied: "You can, if you're willing to pay another quarter of a trillion dollars to do so." During the interview he asked whether the counterterrorism combat in Afghanistan served the United States national interests any longer. "If it isn't in our direct national security interest and if there isn't a logical exit strategy and if we don't know what the cost is going to be in terms of money and human lives, then I think you have to say it's probably time we re-evaluate this," Huntsman said. "My hunch is the American people want to be out of there as quickly as we can get it done," he said. But, he added: "You're going to have to leave behind some presence, probably not 100,000 or 120,000 troops, but some presence." In response to Afghan President Hamid Karzai's Nato warning for an end to airstrike over Afghan houses, Huntsman said: "If President Karzai continues with these public ultimatums, we must consider our options about the immediate future of US troops in his country." "If he actually follows through on his claim that Afghan forces will take "unilateral action" against Nato forces who conduct such air raids to take out terrorists and terrorist positions, that should result in the immediate withdrawal of U.S. forces from Afghanistan and the suspension of U.S. aid. I still firmly support our mission in Afghanistan, but we must have the support of the host government. Our troops' mission will be compromised and their safety endangered if the Afghan government threatens us." Coalition troops are expected to begin leaving Afghanistan in couple of weeks at a time when Afghanistan is experiencing the worst wave of violence ever since the beginning of combat in the country.
