Moscow (AFP) – President Vladimir Putin says that Russia’s nuclear triad — weapons delivered by land, sea and air — is “much more” advanced and modern the United States’s, warning that he was ready to deploy the weapons if Russia’s sovereignty was threatened. The Kremlin has touted its nuclear prowess throughout its two-year offensive in Ukraine, and warned Western countries last month that there was a “real” risk of nuclear catastrophe if they escalated the conflict.
