“love to use civilians as shields” is the most “I believe shooting civilians to kill combatants is justified” ass shit ever written. Every time one of you civvy killing sons of bitches say that, I hope you flash into a universe where your family is killed and you are personally blamed for it. Experience your own violence.
You cannot target with an explosive detonated at random. Lemme detonate a bomb next to your kid on a bus and see how you fucking feel when I tell you he was collateral and untargetted. See if that makes you feel better.
