What prompted the United States to send supplies to Israel during the Yom Kippur War of 1973 is the Egypt’s support of Syria.

In 1972, Anwar el-Sadat ousted and excluded 20,000 Soviet advisers from Egypt and started new diplomatic channels with Washington, D. C., which, as Israel’s key ally, would be a vital mediator in any future peace talks. Sadat formed a new alliance with Syria, and an attack on Israel was planned.

When the fourth Arab-Israeli war opened on the 6th of October 1973, a lot of Israel’s soldiers were away from their posts observing Yom Kippur - - - Day of Atonement. Arab armies made a strong impression on their advances with their up-to-date Soviet weaponry. Soon, Iraqi forces joined the war, and Syria was supported by Jordan.

Many days after, Israel was fully mobilized. The Defense Forces of Israel started beating back the Arab gains at a huge cost to soldiers and equipment.

Airlift of arms of United States aided Israel’s cause, but as a tactic signal of the United States' sympathy for Egypt, President Richard Nixon (1913-94) delayed the emergency military aid for a week.

An Egyptian-Israeli cease-fire was secured by the United Nations on October 25,
