The Overseas Contingency Operations fund, which will receive 85.3 billion in FY 2018, is outdated and should be done away with. It was born out of the Budget Control Act of 2011. The BCA put spending caps on discretionary spending (among other things). At the same time we had over one hundred thousand troops in Afghanistan and they needed, and deserved, funding unaffected by budgetary constraints, so the OCO was created as a way to finance the Afghan war.
Today the Overseas Contingency Operations fund is unnecessary. It is a loophole that was created for a good reason, but that reason no longer is valid. President Trumps budget chief Mick Mulvaney has correctly called the OCO a military slush fund, and in 2014 proposed a bipartisan amendment to the House defense bill limiting what the OCO could be used for.
The OCO is not being used as it was originally designed. If the Department of Defense wants to fund a US military infrastructure overseas they should put it in national defense budget and have that budget approved by Congress. When Congress approves funding for the OCO, they have no say on how it is spent.
I say it's time for a change. We need to get back to being fiscally responsible. We cannot keep walking towards the fiscal cliff.
