Putin’s comments came in a letter to participants in a UN conference to reaffirm the nuclear non-proliferation treaty that began on Monday. “We proceed from the fact that there can be no winners in a nuclear war and it should never be launched, and we stand for equal and indivisible security for all members of the world community,” the Russian leader said. The remarks were a sharp departure from the Kremlin’s constant reminders of its nuclear capability during the last five months of the war in Ukraine.

He said as a result of these conflicts, “humanity is only one misunderstanding, one miscalculation away from nuclear annihilation.” “Future generations are counting on your commitment to walk away from the abyss,” Guterres told the assembled politicians and diplomats. “This is our moment to meet this fundamental test and lift the cloud of nuclear annihilation once and for all.” Putin threatened Western nations with “unseen consequences” for interfering with his invasion of Ukraine.Dmitry Azarov/Kommersant/Sipa USA (Sipa via AP Images One hundred and ninety-one nations are parties to the non-proliferation treaty.
