During a December 1974 conversation between Soviet Ambassador Anatoly Dobrynin and US Secretary of State Henry Kissinger, Kissinger expressed frustration over the public release of a Soviet letter amid sensitive trade legislation in Congress. The discussion also covered U.S. and European coordination on the Pan-European Conference and ongoing Middle East negotiations, with Dobrynin warning that US unilateral actions risked undermining broader peace efforts and US-Soviet relations.
