Only their leader/dictator is strong.
A country needs to be strong in the US-style if it wants to be the world's cop or just an aggressor to keep its swamp fat and happy. That's why we have those idiotic aircraft carriers - 13 to be exact and have been in the state of war 90% of the US existence - and always somewhere else.
Russia wants neither, but it didn't forget its 30 million dead and the unhappy events that led to this because it was weak enough to temp a moron.
If Russia were really weak, Crimea would be part of Ukraine again. It is not and never will be.
It's not enough.
It depends on the objectives. The USSR learned its lesson in Afghanistan. They don't need that kind of strength.
