Re Sweden and Finland and NATO:
"Russia, Putin said, had no problem with Finland or Sweden, so there was no direct threat from Nato enlargement which included those countries, Reuters reports."
One word: Vyborg. I don’t think that Finland has forgotten or forgiven the USSR for taking over this city in 1944.
Nor has Russia played down that they acquired it by force. Quite recently, March 25, 2010, Dmitry Medvedev named Vyborg the "City of Military Glory".
Whilst Finland might have had reasonable relations with Russia, they are acutely aware of how exposed they are.
