Millions of Muslims dead and the world wonders why the West is hated?

Stephen Walt asks why the US is so shocked when Muslims want to kill their citizens:

Some degree of anti-Americanism may reflect ideology, distorted history, or a foreign government’s attempt to shift blame onto others (a practice that all governments indulge in), but a lot of it is the inevitable result of policies that the American people have supported in the past. When you kill tens of thousands of people in other countries — and sometimes for no good reason — you shouldn’t be surprised when people in those countries are enraged by this behavior and interested in revenge. After all, how did we react after September 11?
