I just new you'd be happy. But bear in mind that we are effectively in a new cold war now, even warm. Ukraine is hot but not part of NATO, although billions of additional $ in money and equipment have been sent, but again the vast bulk of that assistance has come from the USA.
The Cold War was a different era, defending against the threat of attack from the multi-state Soviet Union - the spending then does not really apply to the present. This 2% NATO spending agreement originated in 2006 and was reconfirmed in 2014, but ten years later, more than half of NATO members are still delinquent.
