Large collateral damage is a percentage.
An attack that targets and harms mostly combatants with little collateral damage is not indiscriminate. I’m curious what the ratio of combatants to noncombatants is before arguing whether this attack was a war crime.
I genuinely believe the NSA et al is targeting those who attempt to avoid all targeting more than the average person. It’s difficult to avoid being tracked, it’s nearly impossible to additionally blend in with an unsuspicious façade. Might as well become a secret agent if you’re capable of avoiding the NSA’s gaze.
