Having done something before should make it easier for you to find sources this time to support your minimizations. And to be clear 50-50 is TERRIBLE and means any more serious operation we initiate is likely to kill a lot of innocent people. We’re not Israel, we only kill one innocent person for every enemy fighter, is not the reassuring statement you think it is.
The idea of “Power is big boom” is horribly antiquated WW2 style thinking.
You have a fantasy where precision guided bombs dropped from 10,000 feet punch cleanly through buildings to destroy terrorist heads and terrorist heads alone with no collateral damage to nearby people or buildings. Power is also having the ability to just shoot up a car because it might be getting too close to your check point, knowing that your overriding priority is maintaining control and protecting your allies and you’ll never suffer consequences for being a little overeager and making an oopsie.
