For 60 years, a hotline aims to keep cool between US and Moscow

Sixty years ago, a crisis hotline for the first time sent a message between the world's superpowers.

Communicated by Washington to Moscow, the message dated August 30, 1963 was more about testing every letter of the English keyboard than about addressing immediate conflict: "THE QUICK BROWN FOX JUMPED OVER THE LAZY DOG'S BACK 1234567890."

But since then, the famed hotline has worked to manage tensions -- or to send warnings -- between Washington and Moscow, whose relations have plunged to new lows over Russia's invasion of Ukraine.

The hotline became reality in the wake of the 1962 Cuban Missile Crisis, with president John F. Kennedy and Soviet leader Nikita Khrushchev agreeing that the world came too close to nuclear war.

Never a literal telephone as depicted in movies, the hotline was originally a clunky telegraph machine with cables under the Atlantic and Europe that each side would test every hour.

The Pentagon, which managed US communications, would often send trivia such as baseball scores while the Kremlin preferred excerpts from classic Russian literature, Howard Patrick, a linguist who helped operate the first machine, said in a 2014 interview with the Pioneer Press in Minnesota.

He said there was shock when the hotline was first put to actual use -- a message from the United States to officially inform the Soviets that Kennedy had been assassinated in Dallas.

The tool's first use to avert conflict took place in 1967 during the Six-Day War in the Middle East. Soviet premier Alexei Kosygin sent an early-morning message to president Lyndon Johnson -- who had already been awoken and briefed but had then gone back to bed -- about Israel's pre-emptive attacks on its Arab neighbors.

The two leaders would exchange 19 messages during the war, according to US officials involved.

The most critical exchange came when Israel fired on a US surveillance ship, the USS Liberty, killing 34 on board in what was determined to be an accident. With US forces racing to the site, Johnson assured Kosygin that the movement was not targeting Russian forces in the Mediterranean Sea.

Kosygin sent a reply, since declassified, in which he called for an "immediate cessation" of the conflict and asked Johnson to apply pressure on Israel.

Johnson became fond of using the hotline to Moscow, known in Washington as Molink, and would send updates on the Apollo space missions.

The hotline again came into use over another Israeli-Arab war -- but in very different circumstances -- in 1973.

Israel, stung by early setbacks after a surprise attack by Egypt and Syria on the Jewish holiday of Yom Kippur, was making rapid gains against the two Soviet allies.

Soviet leader Leonid Brezhnev proposed to Richard Nixon that the superpowers both send forces to the region -- an idea US officials thought would be disastrous -- and then warned through the hotline that Moscow was considering sending troops on its own.
