Putin has ascended the throne so long ago that it seems he was always there and everything else is just legend. In the first period of his reign he clearly sought to integrate Russia into the Western world. This is evident not only from his public speeches, but also from the fact that he was the first world leader to call President Bush after 9/11. He did not simply express his condolences, but also helped with intelligence on Afghanistan and agreed to a US base in Kyrgyzstan.
He told Kim Jong-il — the second dictator of the North Korean Kim dynasty — that he remembered the smoke of burnt documents billowing from the windows of the Stasi as he stood on the square among onlookers — and that if the Great Leader did not want this to happen in Pyongyang, he should make concessions (I cannot cite the source of this information, but it is more than reliable — take my word for it).
But integration did not work out. Putin did not just want to enter the club on equal footing — he wanted to join its privileged, senior members. Moreover, he did not understand the rules of this club, thinking that everything remained as it was at the end of WWII, when the leading countries divided the world among themselves — and he wanted to be among those leaders and partake of the division. But while Churchill and Roosevelt, given Stalin’s capabilities and ambitions at the time, might have had no choice but to agree with him, the world had changed since then. And it is not just that ever since the beginning of Putin’s rule Russia has been militarily weaker than the post-war USSR.
