The Pentagon budget is $146 billion higher than when Trump left office. Between last month's regular appropriations and this week's war supplemental, the 2024 Pentagon budget will be at least $953 billion. Adjusted for inflation, that's more than the average annual U.S. military budget during World War II. A trillion-dollar Pentagon budget used to be hyperbole; now it's almost reality. Lawmakers who want to move toward a more sensible level of military spending should know two things. The first is that public opinion is on their side. The second is that public opinion is not enough to challenge the arms industry's influence over Washington public pressure on Congress is needed. Political leaders demand a cash-strapped public to fund a foreign policy that's deeply flawed and incredibly expensive. As a practical matter, the Pentagon hasn't shown that it can even manage such gargantuan budgets, having never passed an audit. More than half of the annual military budget goes to private contractors, and the Pentagon allows these contractors to overcharge taxpayers on almost everything it buys. The arms industry goes great lengths to keep it this way. Military contractors fund influential think tanks to give their profit-driven demands a scholarly gloss, retain more lobbyists than Congress has elected officials, and pour tens of millions of dollars into elections. These tactics work. For instance, before voting to authorize $886 billion in military spending this year, each House member had received on average $20,000 in political donations from military contractors this election cycle. House members who voted for the bill accepted four times more arms industry cash than those who voted no, on average. Senators who supported the bill took five times more, on average. This correlation has been apparent in each of the last three years.
