Okay? I may be slow right now or something, what is the question here?
There were many anti-communist leaders during this time who unfortunately looked to Mussolini for political inspiration, although the most famous would have probably been Hitler.
The American Civil War was a totally seperate issue to the Mexican War. Thats like equating the American War of Independence and saying that it was a direct cause for Vietnam.
The answer is the 1st one. Hope it helps :)
