I want to know the answer to the following question:
Who was the military theorist in 1939 who said 250,000 deaths and injury could occur in the first week of war in Britian?
All the background I'm provided with is that "In 1939 military theorist Basil Liddell-Hart predicted that 250,000 deaths and injuries in Britain could occur in the first week of war.". Is that enough to answer the question?
