I want to explain why the Defence world is devastated at John Healey's resignation. In every other Dept of State, the worst thing imaginable is manageable - pandemic, flood, riot, even a bond market selloff. Defence people prep, 24/7 for the unimaginable. Today someone stood up for Defence - not "against" HMG but against the public complacency that's limiting HMG's options. No other SecDef has done this... so let's hope this turns the tide.
