The first Budget in Obama's term put the war spending on budget.
They were off budget during Bush's terms but one of the first acts Obama did with a democrat congress was to put them on budget.

Now, people may think "good, we need to account for that money anyways" but the fact is they were always accounted for in the end. The problem with this is the rules of congress say you have to pay for new spending. With the wars off budget, when congress decided to do something new or increase something, they had to either decrease somewhere else, raise taxes, or assume an influx of revenue with a realistic chance of it happening. Now, when the wars wind down, congress can simply spend the money as new spending without having to at minimum look for it.
Note, I saw some articles saying that we are still using some supplemental appropriates (off budget) for spending on the wars. I am led to believe this is minor compared to the on budget spending for it.
