La Russia ha il più grande arsenale atomico al mondo e il presidente Vladimir Putin ha minacciato più volte che potrebbe usare armi nucleari in Ucraina o contro chi interviene nella guerra. L'omologo statunitense Joe Biden afferma che Mosca non sta bluffando.
Quanto è reale il rischio di un conflitto nucleare? Quale sarebbe l’effetto dell’uso di armi nucleari tattiche sul terreno? Ha senso controllare i rifugi anti-atomici in Svizzera?
Stephen Herzog, esperto in armi nucleari all’istituto per gli studi di sicurezza del Politecnico federale di Zurigo, è stato attivo nel controllo di armi nucleari per il dipartimento dell’energia degli Stati Uniti; Alan Crameri e Bettina Müller lo hanno interpellato per questa puntata del podcast settimanale "Il mondo là fuori".
