Err... $3.5 trillion?QuoteIn Iraq, 4,000 US troops have been killed, 58,000 wounded, and 100,000 have returned home with serious mental disorders. Stiglitz and Bilmes estimate that the USA's total lifetime medical, disability and social security costs for the two wars will be $717 billion through to 2017. They estimate that the war against Iraq will cost the USA a total of $2.65 trillion through to 2017. The war on Afghanistan will cost another $850 billion through to 2017. The total is $3.5 trillion. (Bush misunderestimated it would be $50 billion, wrong by a factor of seventy.) This works out at $25,000 for every US household. The costs of the two wars to the rest of the world are another $3 trillion, largely because the invasion has driven up oil prices from $25 a barrel to $120. This has cost the world $800 billion so far, and will have cost an estimated $1.6 trillion by 2015. The First World War cost the USA $577 billion, the war on Korea $295 billion, the war on Vietnam $670 billion and the Gulf War $94 billion. The total cost of these four wars was $1.64 trillion, which is just half the cost of the two current wars. Ouch !
