Washington (CNN) - As President Obama prepares to announce that he's sending more troops to Afghanistan, comparisons to the war in Vietnam are often invoked.
But experts say while there are similarities between the two conflicts, there are more differences.
U.S. and coalition forces have been fighting in Afghanistan for more than eight years, initially rooting the Taliban from control after the September 11, 2001, terror attacks against the U.S. because of its support of al Qaeda terrorists who carried out the attacks.
But after the U.S. went to war with Iraq in 2003, the Taliban regrouped, and fighting with U.S. and coalition troops has escalated.
In March, Afghanistan will become America's longest war, surpassing the one in Vietnam, which cost more than 58,000 American lives.
