Reckoning the costs of war in Iraq will take years. Using federal government and other sources, analysts at the Center for American Progress have calculated an 'Iraq War Ledger.'
The costs of military engagement in Afghanistan and Iraq account for well over one-quarter of the increase in US national debt since 2001. Financing wars and defense build-ups in this way is an historical aberration. Americans have typically paid for wars through higher taxes.
At the NATO summit, President Obama's push to soften troop withdrawal deadlines could bring remaining war costs to $413 billion, according to one independent analyst.
Funding for war in Afghanistan will eclipse Iraq for the first time in next year's budget.
A move out of Iraq could save America $370 billion.
The Iraq war has cost taxpayers about $526 billion so far – and could reach $2 trillion by 2017, according to one congressional study.
New book says war will cost at least $3 trillion before it's over.
