After the downfall of the Soviet Union, the Russian Federation was on its way to integrating itself into the Western community politically, economically and socially (by Western World I mean the so-called "First World" countries like Germany, UK, France, Italy, Japan, USA and so on). After Putin followed Yeltsin, not much changed. Soon, powered by high oil prices and good relationships to Western investors and companies, Russia became more and more wealthy and overcame the transitional crisis it suffered in the 90s. Western Companies started to build more and more facilities in Russia. NATO even declared that Russia was no longer a threat and Russia and NATO even started partnership projects.
But suddenly, somewhere after the financial crisis, Russia became hostile to the Western World again. It attacked Georgia, it attacked Ukraine, it started to support Anti-EU-parties in the EU and perform risky maneuvers near NATO ships, spreading horrible lies about NATO, EU and the USA in TV and on the Internet and threatening NATO.
Why this sudden turnaround? Soon after Russia began to stop integrating itself into the Western community, the wealth stopped and Russia's condition become worse and worse, economically speaking. When did this happen and what could be the reason(s) for the decisions behind Russia's actions? Was it the Financial (Subprime) Crisis? Was it America's Intervention in Iraq (but this happened way too much earlier)?
