So what? It was one of two sources, the Russian one claimed to be it is the second, business insider claimed it is first. Given that weapon trade is not the most public one, I expect great uncertainties about this, so I personally would not guess who is right here. You may have a point here, the weapons market seems indeed much smaller than presented by some anti-war-propagandists who tend to present it as very large. Whatever, the more important point is that for Russia the export and import is much less relevant than, for example, for Norway or Saudi Arabia. Simply because the economy as a whole is greater, and the role of the inner market is more important in comparison with the foreign markets. Source?
