The US has gone on a world-wide paroxism of violence for 20 years, and naturally the effects reach the US as well as other countries.

There is a lot of violence in the human world (though humans are less violent than apes, and modern society is less violent than it was before). It is unfair to judge yourself as others as "complicit" in all that violence. Just having something in common with those responsible is not enough grounds to deduce complicity.

But it does mean we should try to reduce the violence.
