On 17th September 2009 – the 70th anniversary of the Soviet invasion of Poland – Obama capitulated to the Russians. He surrendered Poland, and the Bush plan to deploy a missile shield in Poland, to the Russians because he naively believed that (as his stupid foreign policy advisors promised), Russia would reciprocate, i.e. back tough sanctions against Iran.
Russia did not.
Ever since 17th September 2009, Obama Administration officials have claimed that they did not make any deal with the Russians. On that one issue, they’re right.
They didn’t sign any deal with the Russians. Obama’s policy was a policy of unilateral capitulation.
