Well there's been several reports from different people saying that trillions of dollars have gone missing from the Pentagon many times, I thought about adding another one.

This article, which is kind of outdated talks about a $10 trillion figure. While not all of that money has neccesarily end up in the pockets of corrupt politicians, the terrible management of the Pentagon is really disturbing. Just a single trillion dollars alone would be enough to boost all institutions in the US. (Education, health care, management of structures) But all of it is lost on the military and probably managing the mansions of politicians.
