I get that we've decided 'NATO Good' now -- but are people really so sure that it's sphere of influence is geopolitically stabilizing?
I don't see how it could be. If I were Russia, or an ally of Russia, an expansionist NATO would be galvanizing for me and would accelerate a counterbalance alliance. Creating a potentially entrenched conflict in countries that have surface-to-surface access to Moscow would be in my benefit. Ukraine falls into that category.
