I admire George Washington greatly, but it did take him 6 years to defeat Britain, when Great Britain had no allies. Germany in World War I had not only Austria-Hungary and Turkey as allies, but also Bulgaria. How would the American Revolution have turned out if the British had had Bulgaria as an ally in that war?
No allies? I would have hoped that you didn’t forget about the Hessians.
Washington, being an intelligent and precision-thinking man, would have certainly taken US industrial and military strength, vastly superior to what he had available over 130 years earlier, into account, as well as the imperialistic belligerence of the Kaiser. The Lusitania would have been the last straw. Remember, neutrality is a two-way street, not the cowering before bullies.
