I will take cynicism out of this equation and still disagree. Highlevel the ability to strike & defend the country (not simply project) is hugely important. However, having a technically proficient group building tooling to increase efficiency, speed, transparency and collaboration-- not to mention technical security, is certainly important. So yes, I would like a more efficient government && hope we can leverage technology to improve it.
Is 18F delivering on this? I don't know, but it is conceptually much more important than 1/19000th of military spending.
