What is Yom Kippur War?
1.
Historic war started on October 6, 1973 between Israel and Three Arab nations (Iraq, Syria and Egypt) when the Arabs sneak attacked Israel on her holiest day of the year (which is a religious national holiday) and even that didn't help them much.
The war was ended by a UN cease-fire order (October 22), shortly before Egypt gets its army completely destoyed.
The combatants met in Camp David (1978) and that led to signing the Israel-Egypt Peace Treaty (1979), for the fear that arabs would lose a war ever again.
Arabs got their sorry asses kicked on Yom Kippur War.
