Trade and friendly relations with Russia would serve the Balts much better. The price of the NATO security blanket is living in constant fear. Fear of a Russian invasion and fear of being abandoned by the west at such time.  For that reason these tiny nations will keep reminding the world how terrible Russians are. 
Lets not fall for it. Russia is not going anywhere it has been there for a thousand years and will continue to exist as long as the rest of us will. Peaceful relations are more beneficial. And the tiny Baltic nations need to learn the advantage of such co-existence. 
As for Crimea it is rightfully where is should be considering the possibility of NATO being invited by Ukraine
to enjoy the Sevastopol Harbor.
