First of all, let me talk about Russia's economic dependence. The distribution of industrial technology in Russia is very uneven. The old foundation left by the former Soviet Union made the whole Russian heavy industry extremely developed, while the wider light industry was extremely backward. Even small commodities such as stockings must be imported. Therefore, the Russian economy is more dependent on the military and energy industries. In addition to energy industry, Russian military industry is still an important way for Russian economic development. After all, at the end of the cold war, a lot of Russian armaments were not needed. If you stay, it will cost a lot of money to maintain it. Therefore, Russian-made equipment was dismantled by Russia and exported for foreign exchange at a lower price.
The second problem is the leakage of weapon performance. Unlike China and the United States, many equipment exported by Russia is still in service in Russia. These weapons are sold to various countries after simple reduction, so it is easy for hostile countries to obtain the real performance of Russian weapons through countries that have purchased Russian weapons. In the event of a war, they can specify corresponding tactics according to the various shortcomings of Russian equipment, so as to win easily.
Therefore, although Russia is a big country in arms sales, in fact, this practice does have some meaning and meaning of eating old money and drinking poison to quench thirst.
