Vladimir Putin is following in the footsteps of his old KGB boss Yuri Andropov, who took the Soviet Union into Afghanistan in 1979 to shore up a failing client in Kabul. To succeed where Andropov failed, Putin will need to devote considerable resources and manpower to save Bashar al-Assad. But there are also significant differences in the challenges the two faced that favor Putin. Saudi Arabia will be his constant enemy, just as it was Andropov's.
In the fall of 1979, Andropov was the principal advocate in the Kremlin of a Soviet military intervention in Afghanistan to keep the communist Afghan government in power. The Marxist Afghan party was rapidly losing control of the country to the mujahedeen, and KGB chief Andropov warned defeat in Afghanistan would destabilize all of Soviet Central Asia. Andropov convinced an ailing Leonid Brezhnev that it would be an easy and cheap victory. In 1956, Andropov had been the Soviet ambassador in Hungary who called for Soviet intervention there, which had kept Budapest in the Warsaw Pact.
