Washington D.C., December 12, 2017 – U.S. Secretary of State James Baker’s famous “not one inch eastward” assurance about NATO expansion in his meeting with Soviet leader Mikhail Gorbachev on February 9, 1990, was part of a cascade of assurances about Soviet security given by Western leaders to Gorbachev and other Soviet officials throughout the process of German unification in 1990 and on into 1991, according to declassified U.S., Soviet, German, British and French documents posted today by the National Security Archive at George Washington University (http://nsarchive.gwu.edu).
What you have represented are not promises and they are not signed accords or treaties, you clown. It is Putin who has violated signed agreements with Ukraine time and time again.
You’re still wilfully ignoring even your own source. Which says, itself,
“the changes in Eastern Europe and the German unification process must not lead to an ‘impairment of Soviet security interests.’
SOVIET INTERESTS. Not RF, not Muscovia.
“assurances throughout 1990 and into 1991 about protecting Soviet security interests and including the USSR in new European security structures. The two issues were related but not the same.”
So, there was only a focus on the USSR integrity being maintained despite unification of the GDR and DDR.
Again, because your lies need to be countered, even your own source is telling everyone that I am right and you’re a Putin shilling liar.
