NATO is being called on, by one of its members, to declare Cyber War on Russia. Russia is accused of causing great financial harm to Estonia via Cyber War attacks, and Estonia wants this sort of thing declared terrorism, and dealt with. NATO has agreed to discuss the issue and make a decision.
More broadly, the nations of the EU have noticed that the Russians aren't exactly innocent lads aggrieved by Estonian insensititivy. The Russians, the EU is noticing, are becoming another thug state with oil:
Russia has suggested it wants to deal only with more established EU members but EU leaders vowed a united stand on Friday, with Barroso calling the Moscow-Tallinn dispute "a European problem."
Participants welcomed their "frank" discussions at the close of the summit in Volzhsky Utyos (Volga Cliff), a picturesque resort complex on the banks of the Volga River, some 1,000 kilometres (621 miles) south of Moscow.
Putin and EU leaders agreed on putting in place an early-warning mechanism for increasingly vital Russian energy supplies to Europe following a request from Merkel after recent gas and oil cut-offs from Russia.
I imagine Estonia is only the eastermost NATO member glad to be a part of this organization with access to American military power should push come to shove. Old Europe might even stop being so confident of soft power's ability to hold off hard power threats to them.
UPDATE: The Washington Post has more details:
Computer security specialists here call it an unprecedented assault on the public and private electronic infrastructure of a state. They say it is originating in Russia, which is angry over Estonia's recent relocation of a Soviet war memorial. Russian officials deny any government involvement.
Botnets were used that slaved one million computers for the attack:
When bots were turned loose on Estonia, Aaviksoo said, roughly 1 million unwitting computers worldwide were employed. Officials said they traced bots to countries as dissimilar as the United States, China, Vietnam, Egypt and Peru.
For a dying country, Russia is fairly loose about alienating potential friends.
