You must be young. Where did we get involved in the past?
Vietnam: we went to war to punish a country that asked Goodyear rubber and Shell oil to pay a part of their profits back to the country. They had no Air force, no Navy but it was needed to protect the people of the United States.
Iraq: We went to war to prevent a man we placed in office from gaining the materials to possibly make an Atomic weapon to bring to the USA and harm us.
Now we have Libya who has a few old planes and a S#$t load of oil. Instead of using our "SMART BOMBS" we send in 120 cruise missiles to hit 20 targets. Now we have millions of Libyans ready to go to Jihad against us who last week were in the streets practicing freedom and the American way.
The answer MONEY. The bankers want troops on the ground so they can loan money and reap profits.
