In this episode of The Security Podcast I am joined by Lord West of Spithead, a former Chief of the Naval Staff and Security Minister and who now sits on the Intelligence and Security Committee. During the podcast, we examine the claim that the West is involved in a Grey Zone war with Russia and how Nato needs to prepare for a potential attack by Putin. We also look at the current state of the Royal Navy, discuss whether the aircraft carriers are white elephants and whether the UK's submarine based nuclear deterrent is still relevant.
