I’ve heard persuasive arguments that Chamberlain did the only thing possible for Britain at the time. Their defense industry was just spinning up and they needed more time to have any chance at facing Germany. The Spitfire had only just started production, for example.
At the start of the second world war, Germany was much less mechanized than other countries. I think the US had one car for every five people, the UK one car for every 10 people, France won car for every 15 people, and Germany one car for every 30 people. Something like that.
The Germans used more horses in World War II than they did in World War I.
The thing was, what they did have they used effectively, including using radios for communications, which none of the other countries were doing at the time.
