As much as it pains me to say, the US is no longer a force for good. It stopped being one sometime during the 90s, when we went to bat for the Albanian muslim illegal immigrants against former allies the Christian Serbs.
Even worse, the US has become a principal force for spreading terrorism. Look at what the US did to Egypt, the destruction of Libya, the spreading of weapons to Islamists throughout the Middle East and North Africa, the loss of Iraq, the cosmetic occasional campaign against ISIS, and the running cover for and assistance to Iran in its drive for the bomb.
