Note that “the war” cannot be blamed for everything; also, that the federal government could spend plenty of money on plenty of things but that alone doesn't mean it _should_ spend money on those things, or that it's the right thing for any government to be doing at all.

Let us see if we can find $113 million.
We could fund the National Park Service, or we could:
buy sugar for 2X the world price, store it, and then resell it at about an 80% loss.
Costing a total of $1.4 billion over 9 years or about $156 million dollars a year; of course, that doesn’t include the extra $2 billion consumers will pay in inflated food costs.
All that for a few closely held companies that account for a miniscule of U.S. farm output, yet do a very good job of raping the environment and paying substandard wages.

So yeah,
The war.

“While the National Park Service has been underfunded for years, the strains on its operations, notably the upkeep of the natural and man-made attractions that it is charged with protecting, have been exacerbated by the enormous drain on the federal treasury of the misadventure in Iraq.

And so the park service, under the guise of streamlining operations and improving safety, is floating a plan to demolish 132 — or nearly a quarter — of the 550 remaining primary buildings in the Delaware Water Gap National Recreation Area.”
