First of all, before Putin took over, Russia was in a state of internal and external troubles. On the one hand, Russia is monopolized by a large number of oligarchs, and the corruption problem is very serious. On the other hand, the western forces led by the United States are not completely satisfied with the disintegration of the Soviet Union. They want to continue to completely split Russia, leaving Russia with no chance to come back to life and room for turning over. So when Putin accepted Russia, it is no exaggeration to say that Russia is in turmoil, and it can even be said that it is the autumn of life and death.
Secondly, under Putin's administration, Russia successfully recovered to the status of the second largest country in the world. On the one hand, Putin carried out vigorous anti-corruption work, eliminated a large number of Russian oligarchs who endangered the country and stabilized the Russian people's hearts. On the other hand, Putin put his modest financial income into the army. The first is to maintain Russia's huge nuclear arsenal and its deterrent capability. The second is to resume the routine flight of Russian strategic bomber units. Finally, it is necessary to revitalize Russia's military industry and make Russian arms competitive in the world arms market again.
Finally, Putin sent troops to Syria in recent years and made a strategic counterattack against the western countries led by the United States. This move ensures Russia's military presence in the Middle East, and at the same time gives Russia a good geopolitical environment again.
