Or have had any part in bringing America into the war on purpose? I don't know if this is a conspiracy theory, I just thought of it while doing some reading for homework.
It seems very convenient that America was brought in and I feel like it would have been very easy for GB to do with the Lusitania.
The sinking of the Lusitania didn't bring the U.S. into the war, so if that was the intent, it didn't work.
But as far as I can tell, that wasn't the intent - it was just an honest bit of weapons smuggling.
