I see, i'll look it up and post the sources regarding israel's intervention on behalf of Jordan.
I will help you:
the midst of the Jordanian civil war
with Palestinians during September
1970, Syria conducted a short-lived
armored incursion into northern
Jordan. U.S. leaders, seeing Syrian intervention
through the prism of Cold War
politics, responded with extensive military
preparations to intervene on behalf of Jordan’s
King Hussein and prepared to block Soviet
intervention on behalf of Syria. When Syria
withdrew its forces after 3 days of combat
with the Jordanian army, U.S. decisionmakers
not only praised the Jordanian resistance but
also concluded that Syria’s withdrawal was a
victory for U.S. statecraft.
Recently declassified material provides
a richly detailed account of how Washington
quickly developed plans, deployed forces, and
solicited Israeli military assistance in response
to the rapidly developing crisis. The combination
of these steps would have allowed U.S. or
encouraged Israeli intervention to save King
Hussein from a potential Syrian onslaught.
Contemporary memoirs, public statements,
and diplomatic cables suggest that several
key international actors involved in the crisis
acknowledged the import of the U.S. military
moves.
