Mexico's Al Zarqawi.
Well we have at least one person that has no understanding of early 20th century North American history. If I were you I would look to Wilson's needless, unwanted, and completely over the top intervention into issues that were none of his business (besides supporting Villa's cause for a time BTW). And after ruining Mexico, less than three years later, his actions leave Europe in political ruins and stir up problems for over 80 years. Both 'causes' were part of his larger 'spreading democracy' nonsense.
Villa may not have been the nicest of people, and he may have even caused some problems needlessly on the US border. But Wilsonian actions in Mexico did not assist in the issue. But it did assist in giving General Pershing a good wandering walkabout eh?
