In the previous post I mentioned Woodrow Wilson's 1914 intervention in Mexico. There is a somewhat different perspective on this episode in John Judis's 2004 book The Folly of Empire: What George W. Bush Could Learn from Theodore Roosevelt and Woodrow Wilson. Judis writes that after sending troops to occupy Veracruz, which turned out to be a "disaster" which incited "riots and demonstrations all over the country" (pp.91-2), Wilson "learned his lesson" and switched to a non-interventionist stance. When his Secretary of War urged Wilson to send U.S. soldiers to Mexico City, he replied: "We shall have no right at any time to intervene in Mexico to determine the way in which the Mexicans are to settle their own affairs...." (p.92) Judis says that "in his policy toward Mexico, Wilson also broke with a century-old view of the Mexicans as Indians who were incapable of self-government." (p.93)
I know virtually nothing about this episode and perhaps other interpretations of it exist. Just passing this on FWIW.
P.s. H.W. Brands, in his Woodrow Wilson (The American Presidents Series, 2003), p.50, notes that "the lessons Wilson learned in Mexico didn't prevent him from sending troops to Haiti and the Dominican Republic, in 1915 and 1916 respectively, when trouble in those countries threatened American interests and Caribbean stability" -- or, at any rate, what Wilson considered to be American interests and Caribbean stability.
