If there are 100,000 soldiers in Afghanistan after this deployment and whatever soldiers there are left in Iraq you can do the math. And this does not include the cost of any equipment beyond assault rifles and grenades. It doesn't include Humvees or their parts etc. or predators or hell fire missiles or planes or boats or ships etc. So just figure $ 1 million dollars per deployed soldier in Iraq or Afghanistan deployed.
What does that mean in real terms? What it means in the starkest terms is that those of you unemployed will mostly not have real jobs until Afghanistan is over and Iraq is over because a real recovery simply cannot happen until these wars are over. Go back and watch what happened after Viet Nam sucked all the money out of the United States. Study the economic statistics. Look at the late 1970s and the early 1980s and how bad it got(a lot like today) only today is much worse because it is worldwide. Then it was just the United States. Now the whole world is in distress. Just like at Dubai World and the Dubai Government not covering the debt. This could trigger more distress as well.
Another problem is that no matter what Obama promises the likelihood that Democrats will be able to support it and be re-elected is about zero. So he may not get the funding he wants unless we borrow 30 Billion more from the Chinese. That may be the only way this could happen. And the Chinese because of variety of world situations might not be happy about loaning us 30 Billion more dollars unless we give them something to sweeten the pie.
But, in the end unless you are hired by something like a new Civilian Conservation Corp like in the 1930s don't expect to have a good new job if you are out of work until Afghanistan and Iraq are over. At least after 10 years Nixon finally ended Viet Nam in 1974. For Afghanistan there is NO end in sight. Financially, the U.S. is on very shaky ground and keeping this war going could put us under just like the Soviets went under between 1985 and 1991.
