The SVR statement says a secret memorandum from the British Foreign Minister in 1942 describes the Soviet presence in the Baltics as "exactly in our interests from a purely strategic point of view."
It also quotes an agent's report from the United States in 1942, referring to a presidential aide identified only as Hopkins — apparently Harry Hopkins, a close foreign-policy adviser to Franklin D. Roosevelt.
"If the Russians want to have the Baltics after the war, then they will get them, but he does not think the Americans will say this publicly," the report says, summarizing Hopkins' position.
This is supposed to take the wind out of the sails of the Riga summit, but at the same time it confirms the truth - that the USSR occupied the Baltics because it saw them as a threat. Willingly joined? See ya later Soviet history :)
Today, I applaud the Russians. Open your archives more! Inquiring minds want to know!
For those of you that are interested in this interesting term "occupation":
Hague Conventions of 1907. Specifically "Laws and Customs of War on Land" (Hague IV); October 18, 1907: "Section III Military Authority over the territory of the hostile State". The first two articles of that section state:
Territory is considered occupied when it is actually placed under the authority of the hostile army.
The occupation extends only to the territory where such authority has been established and can be exercised.
The authority of the legitimate power having in fact passed into the hands of the occupant, the latter shall take all the measures in his power to restore, and ensure, as far as possible, public order and safety, while respecting, unless absolutely prevented, the laws in force in the country.
