I just looked up what the US spends on defence.

Don's link says that shows the cost of the war in Iraq and currently is just under US$ 72,000,000,000.

US defence spending 2000 was around US$400,000,000,000.

so if you open Don's link and watch as the number increases, note the rate of increase. Then try to imagine what that would look like at five and a half times the speed - that is what was being spent in 2000, when there was no war in Iraq and no war on terror.
