I am also an advocate for nuclear policy, nuclear disarmament, and for eliminating the looming threat of nuclear weapons. The nuclear threat is a topic that has, and does, affect essentially every facet of global history since the development of this technology in 1945.
This is a topic that doesn't just affect politicians, or the military, or world powers, or seemingly remote places on the other side of the world. There is no such thing as a 'limited nuclear engagement' or 'tactical nuclear weapons'. There will be no rules in nuclear war, and these are not conventional weapons - they destroy entire cities and ruin the vast outlying areas for habitation. They are not to eliminate 'military objectives', but to eliminate civilization. As a scientist examining the estimated and modeled data, nuclear engagement (of really any scale) will have massive extinction-level impacts to Earth's biodiversity.
This isn't a topic just for presidents and world leaders to be informed about and discuss - it affects every single person on Earth; therefore, we should all be informed and have a voice in preventing our own extinction. To learn more about this topic, and about organizations that are fighting for our future, check out: the William J. Perry Project, the Perry Project’s At the Brink podcast, the Ploughshares Fund and their podcast NukeTalk, Alex Wellerstein's NUKEMAP, the Nuclear Threat Initiative, and the Union of Concerned Scientists.
