Nixon went on a foreign excursion in summer 1974 starting in Austria, then proceeding onto the Middle East, Portugal, a NATO summit in Brussels, and notably concluding in Moscow. He talked arms reduction with Brezhnev, who he notably got along with better than any other American president. But nothing came of it, as the Soviets clearly understood that Nixon's power at home was all but shattered. Nixon knew it too, of course. The trip had been organized as a last ditch to change the subject, rebuild the president's image a little, maybe even somehow come home with another diplomatic coup akin to the China rapprochement.

This trip, while it has been organized since well before the worst of this crisis arose, feels eerily similar.
