The war in Iraq and in Afghanistan is now $12 billion a month, and the total for Iraq alone is nearing a half-trillion dollars, independent congressional analysts say . The $12 billion a month "burn rate" includes $10 billion for Iraq and almost $2 billion for Afghanistan, plus other minor costs. That's higher than Pentagon estimates earlier this year of $10 billion a month for both operations. Two years ago, the average monthly cost was about $8 billion. Among the reasons for the higher costs is the cost of repairing and replacing equipment worn out in harsh conditions or destroyed in combat.
