Strange. Last I checked the US arms many countries that share borders with friends. The Netherlands didn't seem to care when the US sold F-35s to Belgium.
Why does NATO exist again?
It’s a defensive pact for smaller countries to protect themselves from Russian aggression and imperialism.
And that’s exactly the problem. Seeking an enemy where there’s one eventually creates it. And lots of arms revenues too.
How is it problem if you want to be protected from someone who has already rolled tanks in your country before?
Maybe you should ask people in Poland, Latvia or maybe even in Ukraine.
