There is little danger that U.S. energy security could be affected by a cut-off of Russian enriched uranium, and thus little reason to be concerned about a potential retaliatory action if the U.S. imposed sanctions against the Russian energy sector.
On March 26, we ran a blog post by Sufyan bin Uzayr subtitled: “The U.S., hooked on Russian enriched uranium, is in no position to impose long-term sanctions on Russia.” In other words, collateral damage from sanctions might include an end to Russia supplying the United States with enriched uranium.
