Cuba isnt the United states. If Cuba wants to station Soviet nuclear missiles that is their business. Noone wants to be associated with the US because they are happy to invade and murder you for wanting change.
North Korea isn't South Korea. If they want to develop nuclear weapons that is their business. Noone wants to be associated with the US because they are happy to invade and murder you for wanting change.
Iran isn't Israel. If they want to develop nuclear weapons that is their business. Noone wants to be associated with the US because they are happy to invade and murder you for wanting change.
Do you agree? If not why not? Do you feel threatened by any of these? By your own logic you feeling threatened does not give you any right to impede on anyones business.
In the same wake if you live in the EU you should appreciate Hungary in its sovereignity seeking closer ties with China.
Problem is that disregarding that the people outside the West perceive the West differently and refuse to play by different rules, leads to more escalations all over the world.
All militaries around the world think in similiar terms. The US and many NATO countries invaded and occupied Iraq and Afghanistan because of some abstract threat they associated with these countries, being on the other side of the globe pretty much. Yemen is kept being bombed to support Israel, despite ships not destined for Israel being able to pass.
The US runs bases all around China to be able to militarily contain China.
Taiwan is given as strategic goal to defend, despite both Taiwand and China claiming "one China" and are just disputing about who is the legitimate government of that One China. So in essencense it is a nation internal struggle, that no other nation should have any business in by your logic.
If NATO is projecting power, other countries will do so too.
