U.S. Defense Secretary Pete Hegseth is turning up the heat on NATO allies, pushing hard for them to commit to a bold new defense spending goal—5% of GDP. That’s more than double the current 2% benchmark, and he’s not just tossing around suggestions. Hegseth says he’s confident a consensus is within reach ahead of the NATO summit in The Hague, and he’s making it clear this isn’t a polite request—it’s a necessity. In meetings held recently in Brussels, he emphasized that deterrence doesn’t come from symbolic meetings or vague pledges. It comes from tanks, troops, aircraft, and the readiness to use them.

“Hard power,” as he calls it, is the real backbone of alliance security—and it can’t just be the United States footing the bill.

Not every country is on board yet, but Hegseth has been walking the line between encouragement and pressure. Some allies are ready to step up, while others are dragging their feet. To help close the gap, NATO Secretary General Mark Rutte pitched a compromise: 3.5% for direct military defense and another 1.5% for other security investments like cyber defense and intelligence gathering. Hegseth backed the proposal and reiterated that the 5% target isn’t just a goal—it’s a done deal in his eyes, and a key part of President Trump’s NATO agenda.

Behind closed doors, there’s undoubtedly some arm-twisting going on, and Hegseth isn’t ruling out using the threat of reduced U.S. support as leverage. The message is simple: NATO needs to be more than a club with a shared history;  it needs to be a coalition that can fight and win, together.
