Sir or ma'am - I'm going to say this as politely as possible...YOU ARE A JACKWAGON.
Do you personally know any American Soldiers, Airmen, Sailors, or Marines? The ones that I know that make it back live with their actions EVERY SINGLE DAY. They grieve for the losses of their comrades, those killed or injured by friendly fire and collateral damage (or your term "misfire"), and sometimes even for the enemy.
Little known fact, there has been more collateral damage inflicted by our current "Commander in Chief" via drone strikes than by any Soldiers' "misfire".
"We sleep safe in our beds because rough men stand ready in the night to visit violence on those who would do us harm." George Orwell
