This is Germany/Bundeswehr we're talking about. They already decided on 100 billion after the Russian attack in 2022, a plan that didn't really pan out. The Bundeswehr is famous for its overspending, backwards/lazy ethics, rampant right-wing/neonazi ties. German, and let's be honest, EU government is - even now - in "play it safe" mode, not even big on words, even less on actions. They fumbled virtually every crisis since the 2000s. They let Orban/Putin puppets run rampant and veto most of the botched little help they provided, and still think he can be reasoned with after 15 years. They thought the same of Russia right up the second until a full scale invasion of Ukraine, 8 years after it started to attack it.
Europe is just hopelessly fractured, with no identity, hazy goals and an increasingly degrading economical power. I wish it weren't so, but we didn't manage to unite the forces of these 27 nations beyond some superficial economical agreements.
