Europe is spending money it should have spent a decade ago, on timelines that assume a threat environment that has already arrived.
The rearmament announcements coming out of Berlin, Paris, Warsaw, and Brussels since 2022 are real. The commitments are larger than anything seen since the Cold War. Defense budgets are moving, procurement contracts are being signed, and the political consensus that once treated military spending as an embarrassment has genuinely shifted.
None of that changes the basic problem: defense industrial capacity cannot be rebuilt on announcement timelines. The ammunition shortfalls that became visible during Ukraine’s 2023 and 2024 offensives were not a supply chain accident. They reflected decades of deliberate drawdown — production lines closed, skilled labor dispersed, stockpiles run to minimum. Reversing that takes eight to twelve years under optimistic conditions.
The 2% GDP NATO target, now being revised upward in some capitals, is also largely a political metric. It measures input, not output. Germany at 2% of GDP in defense spending is not the same military force as Poland at 2%, because Poland retained institutional seriousness about its threat environment and Germany did not.
There is also the question of what Europe is rearming for. Territorial defense of the eastern flank against a Russian conventional incursion is one scenario. Extended deterrence without a U.S. nuclear backstop is a different and far more demanding one. The current spending surge addresses the first case inadequately and the second case barely at all.
The rearmament is necessary. The pace is insufficient. And the window between current capability and the scenarios that might require it is narrower than the press releases suggest.
