About NATO — this is a cover for the US to have an “alliance”, that’s the benefit. However this should again be changed for the other countries to pull their weight and spend 2% of their budget on defence
re: defense spending as proportion of GDP in relation to NATO.
The UK does spend 2%+. Have you seen our fancy new aircraft carriers? They’re no Nimitz class, but they’re quite nifty.
France spends about the same.
