When Russian Pres. Vladimir Putin invaded Ukraine, the world came together to send him a message by placing many of the firms that prop up Russia's military under sanctions. While it could initially be argued that they didn't go far enough or they had little impact, two years later we're starting to see the measures restrict Russia's military as well as the livelihood of its general population, turning them against their leader. The sanctions are having a positive impact.
Despite the West's big talk on sanctions, ask any politician about dual-use equipment being used by Russia and they'll go silent. In fact, when you look at who is providing Russia with this kind of gear, you'll find that it's not firms from China or Iran — but indeed companies in the US and Europe. Part of the problem is that despite the wording of the sanctions, there are insufficient means of enforcing the measures. As a result, sanctions are having little impact.
