Up to 35,000 non-Afghan Muslim fighters travelled to Afghanistan between 1982 and 1992.  Thousands more did not come and fought, but attended schools with “old and future combatants”.  These “Arab-Afghans” had a marginal influence on jihad against the Soviets, but a much greater effect after the departure of the Soviets and in other countries. (After the departure of the Soviets, training continued and “tens of thousands” of about 40 nations came to prepare for armed uprisings “to bring the fight home.”  The Soviet Union also supported Daoud Khan Sanism against Pakistan.  The Soviets wanted to weaken Pakistan, an ally of the United States and China. However, it has not openly tried to cause problems in Pakistan, as it would damage the Soviet Union`s relations with other Islamic countries. So she was counting on Daoud Khan to weaken Pakistan. Similarly, the Soviet Union wanted to weaken Iran, which was another important ally of the United States, without harming its relations with Islamic countries. The Soviet Union also believed that Afghanistan`s hostile behaviour towards Pakistan and Iran would drive Afghanistan away from the West and force Afghanistan to strengthen ties with the Soviet Union.  Pro-Soviet Afghans also supported Daoud Khan`s hostility to Pakistan, as they believed that a conflict with Pakistan would favour Afghanistan for help from the Soviet Union. As a result, pro-Soviet Afghans could exert their influence over Afghanistan.  Daoud`s median path ended in disaster. On April 28, 1978, soldiers allied with Taraki`s “Khalq” faction attacked the presidential palace where troops executed Daoud and his family.
In the following days, Taraki became Prime Minister, and in an attempt to end the divisions of the PDPA, Karmal became Deputy Prime Minister. In Washington, this communist revolution was alerted. The Carter administration understood that Taraki Daoud`s attempt to hijack Afghanistan from Moscow would be quashed and discussed whether to sever relations with Afghanistan or whether to recognize Taraki in the hope of curbing Soviet influence. Although Presidential Assistant for National Security Zbigniew Brzezinski supported the earlier direction, Carter supported the Foreign Ministry`s commitment to recognition. Shortly after the revolution, Washington recognized the new government and quickly appointed Adolph Dubs ambassador to Afghanistan. Until his abduction and death by Afghan Shiite dissidents in February 1979, Dub persecuted strong relations with the Taraki regime in the hope that U.S. support would keep Soviet influence in check. In Southwest Asia, radical changes took place at the same time as the unrest in Afghanistan. In February 1979, the Iranian revolution ousted the U.S.-backed Shah of Iran and lost the United States as one of its most powerful allies.  The United States then deployed 20 ships to the Persian Gulf and the Arabian Sea, including two aircraft carriers, and constant threats of war were made between the United States.
