> Under NATO nuclear weapons sharing, the United States has provided nuclear weapons for Belgium, Germany, Italy, the Netherlands, and Turkey to deploy and store
Btw if it's either NATO or nuclear bombs, why didn't Finland get nuclear bombs in the last 60 years?
Finland is a small country and nukes are very expensive (and hard) to deal with all the way: development, manufacture, deployment, service. The pressure to have your own nukes is low when you consider an attack unlikely, which was the case for Finland for the last 60 years.
Countries that did not feel so safe moved much faster (considering different fates of Mr. Gaddafi and Mr. Kim). But recent Russian actions motivated a lot of its neighbors who were not worried before to spend whatever is needed to make an attack on them prohibitively expensive.
As for Finland during the Cold War, not sure if it had a pathway to NATO, same as modern Ukraine, or if the USSR would give it time to develop a bomb. They treaded carefully and forfeited a great deal of their independence.
Finland's policy was one of soft appeasement. The Russian invasion of Ukraine has revealed this to be a bad idea, so Finland continuing as it was is no longer a responsible option.
