Glenn Greenwald writes:

If you want your country to rule the world as an aggressive and militaristic empire, then accept the inevitable consequence of that: that there will be huge numbers of people in the world who resent and even hate your country for that behavior. Don’t cheer while your country constantly kills, invades, occupies, and dominates the internal affairs of countless other nations – and then expect to be liked. Immorality aside, producing this reaction is one reason not to do such things. This kind of imperial behavior, inevitably and in every era, generates extreme levels of animosity and, ultimately, returned violence.
