I am not so sure. Do you really think that anybody important in the west will start WW3 just because some idiots in Estonia? Anyhow this could turn into a really funny litmus test of a totally overblown NATO. You should know that in this case NATO does not just fail against some irrelevant camel drivers in Afghanistan like in the moment. The Russians still have a quite impressive arsenal of conventional and non-conventional weapons and they are really motivated to defend their zone of influence.
NATO is a defensive alliance with many cracks and fissures. Such alliances work the better the fewer members they have. Until 1990 we had 16 member countries and a pronounced concept of the enemy. Today we have 26 members, some good friends in Moscow (with a "near-democracy") we are building pipelines with and a few people who seem to be totally addicted to the bloody past. No - most of the west does not share your personal view of the Russians. Of course there will be some heartbreaking cant if the Russians i.e. think about "saving" their minority in Estonia through a limited invasion, but you should not even think about a real slugfest between the bigger forces in Europe. Our politicians always have been extremely pragmatic (this includes the Americans). You Poles should know that best since this kind of pragmatism was paid by 6 million of your compatriots with their lives. Therefore you are well advised to think about the situation that you could end up in fighting out your WW3 alone with the Russkies. Have fun.
If someone wants protection, support and backing he has to reassure himself among his allies. As we saw in Iraq even the most powerful nation on this planet has to do so. There were many who did not follow although the administration in Washington could not imagine that this would happen. In this case (the graves of those soldiers in Tallin) I am quite sure that nobody sane among the decisive powers in Europe will even think about helping Estonia against the Russians. If you or your gouvernment want to die in heroic action against the Red Army you are of course free to do so. Nevertheless you should not expect too much compassion for such cretinism. At least you have a good chance to win the Darwin Award then.
Crystal-clear democrats. I know.
