I think Russia's move is really about getting rid of its dependence on the West.
Since the development of Russia's defense industry is very slow, which makes a lot of military industrial parts need to be imported from the West, however, as the West has tightened sanctions on Russia, Russia wants to get these Western countries, military industrial parts, has become an impossible thing.
First, Russia wants to realize 100% industrial import substitution, indeed, in order to get rid of the control of the Western countries.If, at the military level, there is a dependence on the West in Russia, then it is bound to bring serious harm to the development of Russia's entire defense industry. Because once by the Western countries neck, Russia's entire defense industry may be paralyzed situation, which for Russia to protect the national security will bring a serious impact so, Russia wants to achieve 100% import substitution of the defense industry.
Two, Russia wants to get rid of the control of the West, is to better confrontation with the West.Only the realization of the independent development of the defense level, can make Russia have more sufficient confidence and the West for confrontation. While the West has very advanced technology, but as long as Russia continues to have a strong military power, the West will not dare to belittle Russia, and in order to maintain a strong military power, Russia must achieve 100% import substitution in the defense industry.
Third, Russia wants to get rid of the West's control, is to fight for more right to speak.While Russia knows very well that once a war occurs, it will bring a very painful cost to both sides, but if you want to get more power of speech at the negotiating table, then Russia must strengthen the deterrent force for the West. And if in the industrial parts rely on Western countries, then Russia for the West's deterrence will be greatly reduced, it is in order to fight for the right to speak advantage, Russia wants to realize 100% of the defense industry import substitution.
