1963: Hotline between the USSR and US established

In light of how close the world came to Nuclear Armageddon over Cuba, this was set up to have the two super powers communicate before before they kill everybody. Contrary to the movies, namely Failsafe, it was never a hotline nor a telephone for the President to call up the Kremlin. The world hung in the balance through a Teletype until 1986. Then came a big upgrade, a Fax Machine. As of 2008, DC and Moscow utilize a secure computer line for something like e-mail. We’re screwed if the POTUS is a Gen Zer given how e-mail is not cool anymore and too slow.
