From Harper's:

Projected cost of disability payments to Iraq War veterans by 2050, based on rates for Gulf War veterans: $285,000,000,000

Number of “veterans of the global war on terrorism” that the VA budget assumed for 2005: 23,553

Estimated number today: 103,000

So if I understand this correctly, the estimated number is actually five times larger than first assumed, which would equal 5 X $285 bil. = nearly $1.5 trillion by 2050....? What?!
