I used to think that way, but now I don't. Brazil implemented a retaliation policy, where U.S. citizens are treated much like Brazilians are in the U.S. Several nice people from the U.S. have had a bad time as a result, and it made me reconsider - I don't think "an eye for an eye" is such a great thing. If only we could only treat people with power to change things that way :) - but someone traveling is already not a standard U.S. citizen and probably more open by default.
