$114 Billion to Israel since 1940
In order to ensure passage along Afghanistan roads the US Government buys security from Trucking Firms that in turn pay off Taliban War lords. So the USA is paying the Taliban to protect the transport of goods. Sick Irony.
The reality is Human Beings are expendable commodities to the World's Leaders INCLUDING the United States.
The answer to your question is follow the money. War is about money.
Jobs mean nothing to the "invisible government".
Obama has asked for $128 Billion for this year for the USA to continue NATION BUILDING in IRAQ and Afghanistan.
If you took that money and created "Jobs" you could create 2.56 Million jobs at $50,000 per year for one year.
Granted that money is not completely wasted ... military equipment is manufactred, soldiers get paychecks, etc.
But it puts into perspective how important American Jobs are to the Government.
Just today it was reported that Unemployment went up in 43 of the 50 States.
Bankers... the Secret Government behind the Federal Reserve does not care about American Jobs or American lives... yet Americans continue to allow them to call the shots and control the money supply.
Americans are misinformed, ignorant, and sadly very easy to control.
