British newspaper The Guardian has published this December 2009 US Embassy cable out of Tallinn, noting the Estonians' welcoming of the decision to expand NATO contingency plans to cover Estonia, Latvia, and Lithuania. Paul Teesalu, director of the Ministry of Foreign Affairs' Security Policy Division, is quoted as calling the decision an "early Christmas present."
Global media outlets have already published NATO's "secret plan" to defend the Baltics in case of Russian aggression. To me, this seems like old news. I've known about the contingency planning for months, for so long that I can't even remember where I found out about it. I have no special security clearance.
This article provides some more detailed information that I didn't know before: "Nine Nato divisions – US, British, German, and Polish – have been identified for combat operations in the event of armed aggression against Poland or the three Baltic states. North Polish and German ports have been listed for the receipt of naval assault forces and British and US warships."
Also interesting is from where the resistance to the contingency planning came. There are the usual suspects: "Attempts [in the past] ... to push through defence planning for the Baltic were stymied by German-led opposition in western Europe, anxious to avoid upsetting the Kremlin." The Germans were later assuaged to back the planning to reassure the edgy Baltics, on the condition that the Baltics agreed to the reset with Russia. But the Poles at first were also hesitant to expanding contingency plans to cover the Baltics. "They did not want the Polish plan to be diluted or held hostage in case other allies opposed adding the Baltic states."
