The shadow of nuclear weapons hangs over Russia’s full-scale invasion of Ukraine. Russian officials have made explicit and implicit references to nuclear weapons in an apparent attempt to intimidate Ukraine and its Western supporters. Russia’s war, moreover, is a further violation of the Budapest Memorandum – the agreement under which Ukraine gave up the nuclear weapons on its territory when the Soviet Union collapsed, returning them to Russia.

In this wide-ranging discussion, the panellists will reflect on the role that nuclear weapons have played in Russia’s war, exploring the implications for Ukraine, the NATO–Russia relationship and potential nuclear proliferation choices in East Asia.
