How wars really get started?

I wonder how much money these Republican senators receive from the defense industry? 

If we are going to consider options, why can't we consider bringing our troops home from Afghanistan first??? This entire charade of war has lasted far too long since it is now been a generation lost for nothing but making Wall Street rich off the blood of American youth. Our nation is foundering like a rudderless ship at sea due to indecision in many areas. We have economic, social, employment, health, environmental, etc... issues many of which stem from the Wall Street takeover of our economy which resulted in our economic collapse. We must cut our losses and might as well begin with stopping the loss of our best and brightest. Am I the only one who remembers stopping the wars being pivotal to the 2008 Presidential campaign??? Time to stop dithering folks!!!!
