The story goes, and it is one I have heard from my rebbeim.
A meeting in 1968 with Senator Hubert Humphrey, then running for the presidency. The rebbe’s aides had warned Humphrey against raising any political issues pertaining to Israel. When he was informed of this after the meeting, the rebbe laughed:
Had Humphrey spoken to me in support of the Zionist state, it wouldn’t have bothered me in the least. We Jews have a Torah which forbids us to have a state during the exile, and therefore we may not ask the Americans to support the state. But a non-Jew has no Torah, and by supporting the state he feels he is helping Jews. So, on the contrary, if an American non-Jew is against the Zionist state, it shows he is an anti-Semite.
