This is a direct quote from Johnson's briefing today:
"And we must act like any war-time government and do anything it takes to support our economy."
He also used some other imagery of war.
I think he does see himself as Churchill (or Thatcher with the Falklands), which is farcical.
Churchill was an inspiring leader, but he left the logistics, decision making and details to the very capable civil servants, forces leaders and other politicians, such as Attlee and Beveridge. Unfortunately, he's managed to p*ss off some of his civil servants over the last few weeks and has only appointed yes men and women to his cabinet.
