Richard Nixon ended the Cold War in 1972, to all intents and purposes.
The Anti-Defamation League of B'nai Brith became rather vocally upset about this, as Henry Kissinger complained to the Israeli Ambassador the following year :
Kissinger warned against the Jackson-Vanik amendment to deny Most-Favored Nation trade status to Moscow. Declaring that the "issue for American Jews is whether a major American foreign policy can be wrecked" - the Soviet grain deal.
"You will really lose the President if the Jewish community continues its behaviour here on the MFN...What if the President [Nixon] went on television and spoke against Jewish pressure?
...I am totally out of sympathy for them..."
- Henry Kissinger to the Israeli Ambassador to Washington,
March 30th 1973
