• The US reduces its material commitment to Europe's conventional defence.
• European Allies need to step up their capacity for immediate response.
• NATO's Immediate Response includes national forces, FLF, and the ARF.
• The European Allies aim to exceed the potentially missing US contribution.

The European Allies' efforts to Europeanise NATO's immediate response may indicate a shift in defence priorities, suggesting that they could take on more responsibility for conventional defence. This development may also signal a need for increased investment in defence capabilities, which could have significant implications for the aerospace industry and the future of NATO's deterrence and defence strategy.
