From The Future of Freedom Foundation:

The conservative case was made by Andrew Lautz of the National Taxpayers Union and Jonathan Bydlak of the R Street Institute’s Fiscal and Budget Policy Project:

With resources more limited than ever, areas of the budget that were off-limits for years should now be more closely scrutinized. At the top of that list should be the single largest part of the federal discretionary budget, an entire category of spending that has long been off the table: the Pentagon.

Republicans in Congress need to start tackling the Pentagon budget just as boldly as they do other areas of discretionary spending. Doing so would put our nation on a better fiscal path and create opportunities for unlikely political alliances. Conservative figures like Sen. Rand Paul (R-Ky.) and former Rep. Mick Mulvaney (R-S.C.) for years advocated restraint at the Pentagon; two of the most recent efforts to restrain the Pentagon’s budget in the coming year come from staunchly progressive members of Congress: Sen. Bernie Sanders (I-Vt.) and Rep. Barbara Lee (D-Calif.).
