It's obviously impossible to wage war with tanks and artillery in a densely populated urban environment without causing large scale destruction and civilian casualties. Whoever orders it can be held responsible for them as if they were intentional.
I have no problem acknowledging that. Especially GW Bush' 'war on terror' has massively eroded the credibility of the West. Its so-called legitimacy also counts for little, given that at the time the US, as the only superpower left standing, was basically capable of strong-arming the entire world into legitimizing whatever insane idea they got into their heads. Take for instance the silly pretext of blaming Afghanistan for 'harboring Al Quaida'. As a casus belli, that certainly falls into the same category of idiocy as 'denazification'. They're all crap reasons.
More petty incidents. Doesn't justify the suffering and destruction of war.
