The Economist writes in an editorial that thanks to Poland, the NATO alliance will defend the Baltics:
When the war in Georgia highlighted NATO’s wobbliness on Russia, Poland accelerated its push for a bilateral security relationship with America, including the stationing of Patriot anti-missile rockets on Polish soil in return for hosting a missile-defence base… the Baltic states will get their plans, probably approved by NATO’s military side rather than its political wing. They will be presented as an annex to existing plans regarding Poland, but with an added regional dimension. That leaves room for Sweden and Finland (not members of the alliance but increasingly close to it) to take a role in the planning too. A big bilateral American exercise already planned for the Baltic this summer is likely to widen to include other countries.
