WaPo explains that when confronted with $125 billion in military waste, the Pentagon tried to bury the report "amid fears Congress would use the findings as an excuse to slash the defense budget:"
Pentagon leaders had requested the study to help make their enormous back-office bureaucracy more efficient and reinvest any savings in combat power. But after the project documented far more wasteful spending than expected, senior defense officials moved swiftly to kill it by discrediting and suppressing the results.
The report, issued in January 2015, identified "a clear path" for the Defense Department to save $125 billion over five years. The plan would not have required layoffs of civil servants or reductions in military personnel. Instead, it would have streamlined the bureaucracy through attrition and early retirements, curtailed high-priced contractors and made better use of information technology.
Salon's Matthew Rozsa reminds us that "the Pentagon's $125 billion waste alone would be enough to fund the world's third-most expensive military:"
Pentagon leaders ... became concerned that the study would prompt politicians in the White House and Congress to cut their budget instead of giving them more money for the projects they wanted, the Post reported. The study was suppressed and its data subjected to secrecy restrictions.
