Russia is a great example. Russia and China push the envelope whenever they can. The idea is that the US won't just nuke anyone that invades someone else, but they can provide ground/air support (sans nukes).
So that's why just having the nukes isn't enough. They're mostly just there so that the US/allies don't get nuked, not good for much else (but very good for that).
