Erm the monarch held no power as head of state during the war years - the few remaining symbolic powers were just that - symbolic. Victoria was the last to actually use one after she was essentially backed into a corner by Palmerston not naming a replacement PM, despite months of avoiding in parliament. That was the mid 1850s.

Now, had you mentioned that a good proportion of the pre-war Tory party were Nazi sympathisers you might be on to something. Notably including Halifax who was offered the premiership before Churchill, after Chamberlain resigned.

'could' exactly. That's the definition of delusion.
