America and its allies will act "decisively" if Russia uses a tactical nuclear weapon in Ukraine, US national security adviser Jake Sullivan said on Sunday, reaffirming the Joe Biden White House's previous response to mounting concerns that Vladimir Putin's threats are in increased danger of being realized.But Sullivan refused to be drawn out on whether the US would change its policy on lifting sanctions in exchange for a nuclear deal in light of the protests."We have communicated directly, privately and at very high levels to the Kremlin that any use of nuclear weapons will be met with catastrophic consequences for Russia, that the US and our allies will respond decisively, and we have been clear and specific about what that will entail," Sullivan told CBS's Face The Nation.
