Repeat a lie often enough and it becomes the truth. You guys are as gullible as the left. That money was not stolen, lost, or missing.
Back then, the entire DoD budget worldwide was around $500 billion annually. Any funds not spent by 30 Sep each year expire and are returned to the Treasury.
The majority of the DoD budget is not sent to the Pentagon for (re)distribution. A small army of accounting types located around the world keep track of all this money. Ever deal with any of them? I have when I served. These are anal retentive folks who take their jobs very seriously.
The military does waste a lot of our tax money. Hint: Dig into the government contracts themselves.
