Rose Gottemoeller, a former chief US negotiator of New START and ex-Deputy Secretary General of NATO, speaks with the Lowy Institute’s Sam Roggeveen about the growing risks of a three-way nuclear stand-off, what the wars in Ukraine and Iran reveal about the future of warfare, and why she will always be a believer in arms control agreements.
