That is nonsense.
When the US attacks other sovereign nations than it's a freedom fight that can't be televised, when someone else does it it's an evil act of aggression.
Yes, it's very tiring. If you're an American, use your vote to demand answers from leaders. If you live in a democracy, reach your politicians, bring the issue on the international level. If you're not in a democracy, work towards the ability to influence the better behavior - that is, work towards democracy.

So, has that ever worked? The US for example still has a law to invade Netherlands if even one of its military criminals is caught and brought to Hague to stand trial.
I am implying that countries with capable military that present themselves as "democratic" don't seem to fare substantially better in this matter.
In fact, the things that are considered ok for them to do are some of the worst examples.
Did democracy help Assange after he had uncovered the evidence of US' warcrimes? Were Bush era "no one will dare to hold the US accountable" laws repelled?
IMO, all it did is helped people "vent out" and "voice concerns" without any real and meaningful change in politics. This all lead us to a point where we see people profiting from war and taking a hypocritical moral high-ground at the same time.
Which in turn leads to that most outside observers don't even take "democratic" states seriously anymore in that matter.
