There was a guy named John Titor who was supposedly a time traveler from the year of 2036. He said that in his timeline in the year of 2015 there will be World War III. Also someone patented his time machine sketches.
In 1962, an intruder climbing the fence at a Minnesota air base set off the “sabotage alarm” in all bases in the area. In one base, due to wrong wiring, the Klaxon was sounded ordering nuclear-armed aircraft to take off, and the pilots believed WW3 has started. The original intruder was a bear.
In 1989, CIA original operative, wrote that in the future, World War 3 would occur when “Soviet Russia” dupes the United States and Israel into waging a self-destructive war with the Muslim/Arab world.
A bear almost caused World War III.
