Roots of Putin's Soviet politics
On July 25, 1998, Yeltsin appointed Vladimir Putin head of the FSB (one of the successor agencies to the KGB), a position Putin occupied until August 1999. He became a permanent member of the Security Council of the Russian Federation on October 1, 1998 and its Secretary on March 29, 1999.
But, on December 31, 1999 Yeltsin unexpectedly resigned and, according to the Constitution of Russia, Putin became Acting President of the Russian Federation.
However, Yeltsin leaned more into the direction of what is called pro-Western. He wanted to reform the Russian economy into a free market economy. Putin was against the reforms and wanted the Soviet system back.
In the video from April 25, 2005 you can watch how he deplored the fall of the Soviet Union.
It is here, and nowhere else were it all began.
