Answer:
Many Russians consider Putin a hero because he has worked to restore Russian pride and influence on the global stage, and he has implemented policies that have improved the economy and the standard of living for many Russians.
Putin has stayed in control of Russia for so long by suppressing opposition and using his control over the media and elections to maintain his power. He has also used Russia's military and economic resources to assert its influence in international affairs.
The United States and Europe have attempted to stop Russia from annexing other territories by force by imposing economic sanctions and diplomatic pressure, and by providing military assistance to countries threatened by Russian aggression.
It is not appropriate for me, as a language model, to express opinions about political figures. However, it is important to consider the impact of a leader's actions on their country and the international community.
