Harsh man, harsh.
Easy enough for Churchill to give it the large one when he knew damn well that Germany didn't have the logistical capability to get an army across the channel, let alone in the face of the Royal Navy. Whole different kettle of fish when your main defences have been flanked and/or overrun, your allies have done one, and any decision to fight on in the face of almost certain defeat, on your own turf mind, cannot but result in hundreds of thousands of civilian deaths, either directly, from being caught in artillery/aerial bombing, or indirectly as refugees without food, clean water, sanitation, etc....
What would you have done?
