Um, it's been a couple of hours but this is what I remember:
--many of the governments there are oppressive, which are happy to let their medias focus on America as bad guys rather than themselves;
--they hate Israel and therefore our support of them;
--they have nothing and don't feel they ever will, while we have lots--jealousy;
--some governments with capitalist economies have done a bad job of improving their peoples' lot (per capita incomes not improved since 1950s)
--so things that symbolize America or a 'successful American life' are objects of derision or targets.
