‘NATO 3.0’ Needs More Manpower

The National Interest  |  Alex Wagner, Kristen Taylor

The upcoming NATO Summit in Ankara, following Secretary General Mark Rutte’s visit to Washington, aims to lock in European defense spending momentum. While the summit will focus on defense spending and industrial cooperation, a critical unaddressed issue is NATO's ability to generate sufficient manpower to provide military credibility to these investments.

The Trump administration's recent announcements, including withdrawing 5,000 troops from Germany and restructuring US force posture, have created significant uncertainty regarding European manpower, weakening deterrence and alliance cohesion. Europe faces significant manpower challenges, including low propensity to serve, inadequate pay, cultural resistance, and demographic constraints, with the EU's birthrate falling below 4 million in 2022. To bolster militaries, increased defense spending must prioritize substantially higher personnel costs, including targeted pay raises and modernizing recruiting infrastructure. NATO allies currently spend an average of just under 35 percent of their defense budgets on personnel; this share needs to grow. Without a larger European workforce, particularly for the eastern flank and Baltics, additional funding will not translate into credible deterrence against Russia.
