Indeed, since 2010, the United States has denied extradition requests from Russia, Bolivia, and Venezuela, for suspects facing charges or convictions for fraud, genocide, and terrorist bombing.[11] These denials appear valid: the United States does not have an extradition treaty with Russia, the Bolivian suspect was charged with military crimes, and the Venezuelan suspect may have been tortured upon his return.[12] More interesting is the American response to the kidnapping and torture of Abu Omar. In 2003, 23 Americans, 22 CIA employees and one Air Force Colonel were involved in the kidnapping and torture of Egyptian citizen, Abu Omar.[13] Omar was taken from Milan, transported to Egypt, and tortured for seven months.[14] The 23 Americans were convicted in absentia in 2009, and the Italian prosecutor wanted the Americans extradited.[15] However, it appears that after the United States made clear it would not extradite the 23 American citizens, and spent years pressuring the Italian government to back down, several Italian Ministers of Justice blocked all extradition requests.[16
I think we don't really care that much about upsetting them.
