Vladimir Putin has spoken several times about using nuclear weapons since Russia launched its invasion of Ukraine in February 2022. However, the initial attention and concern that global news media gave to Putin when he first spoke on the issue in September 2022 seemed to have largely dissipated over the past two years of conflict, perhaps because of the frequency with which he has threatened to resort to use of Russia’s nuclear arsenal.
Now Putin has issued his strongest threat yet, saying that Russia would use nuclear weapons against any country attacking it, even with conventional weapons. This statement appears to be intended to influence the debate happening at the United Nations, where Ukrainian president Volodymyr Zelensky is trying to persuade his country’s western allies to allow Ukraine to use the weapons they have provided against targets deep within Russia itself.
This has been a “red line” hitherto that Ukraine’s allies have been unwilling to cross. That may be about to change though and Russia’s reaction has been to reiterate a nuclear response.
