Nonsense. The civil war started long before the USA became involved
July 1973 the Marxist PDPA stages a military coup, overthrows the
monarchy and installs Mohammad Daoud Khan as Prime Minister
His policies are deeply unpopular and mass demonstrations in Kabul
are brutally repressed..
April 1978 another military coup overthrows (and murders) Daoud
and installs his PDPA rival Nur Muhammad Taraki.
Mid 1978 rebellion breaks out in Nuristan and spreads throughout
the country as a result of the 'modernization' policies of the new
government. The PDPA resorts to traditional terror tactics to
put down the rebellion with thousands being executed in the
Pul-e-Charkhi prison for opposing government policy.
By spring of 1979 revolt has spread to 26 or the 28 provinces.
September 1979 another coup installs Hafizullah Amin as leader and
he starts backtracking on the policies. This does not go down well
in Moscow and the leadership decides to intervene.
December 1979 Soviet forces cross the frontier and begin moving into
Afghanistan in overwhelming force. and Soviet special forces
take control of Afghan government buildings, overthrow Amin
installing Babrak Karmal. To their consternation he is livid warning
them that they have ignited the fuze to a powder keg.
He is right within weeks over 50% of the Afghan army has defected to the
rebels along with their heavy weapons . The government controls less
than 20% of the country. The Soviets launch a series of punitive raids
into rebel country but take heavy losses and as soon as they withdraw the
rebels come out of hiding again.
The US only becomes heavily involved after the Soviet invasion by which time
the rebellion is well established.
