How would you know what voice they raise? You're getting it filtered through the American press, and the voices of those normal citizens in other countries are also being filtered by their own media. Anyway, a huge chunk of the American population went along with the Bush Wars, and believed outright propaganda (many still cling to it). Sure there were dissenters, but the didn't get so much airtime as the war hawks, if you recall. Prior to rise of the internet, US Forces conducted some totally brutal campaigns in Latin America and very few Americans dissented or ever knew the details - it didn't go with the official statements which the TV and newspapers reported - this is stuff you can research now very easily, but the vast majority of Americans are still oblivious. Given the general American lack of consciousness or caring about the history of American atrocities, how can you criticize residents of a third world country - many of whom do not have even electricity, TV or internet access, and many who are under oppressive regimes who censor their speech with disappearance, jail or death - for not "raising their voice".
