A look at the costs of Afghan war to US taxpayers

U.S. President Barack Obama's request for more money to pay for the war in Afghanistan is working its way through Congress slowly as lawmakers concentrate on other priorities and deal with scarce budget resources. Obama has asked for $33 billion more to help fund 30,000 extra U.S. soldiers being sent to Afghanistan this year. He wants $4.5 billion more for beefed-up foreign aid and civilian operations in Iraq and Afghanistan this year; about $2 billion of that amount is dedicated to Afghanistan. The House of Representatives approved the funding last month and added billions of dollars in non-military spending, meaning the measure must return to the Senate for final approval. Lawmakers are expected to pass the funds, but are also demanding assurances that the government of Afghan President Hamid Karzai tackles corruption to ensure U.S. taxpayer dollars are not wasted. Following are the costs to U.S. taxpayers so far, as well as some of the future funding needed.
