Europe needs to be made to pay more for its defense, accept that it is a US protectorate, and comprehensively bend the knee to the US on other issues in consequence of its status as a protectorate.
In fact, NATO outside of the US will COLLECTIVELY meet the 2% of GDP defense spending guideline in 2024.
Arguably they get less bang for the buck, er, Euro, so in a time of moderate conflict or tension, like the present, that figure probably needs to be amended to 2.5%.
