Cecilia. Just do your best. It is going to happen anyway, so stay strong and make the most of it.
Krayav. I firmly agree that violence can cause future problems and that it can hurt innocents. Hiroshima was necessary. The Japanese people, men, women, and plenty of children were ready to die for their emperor. Not to mention how many military casualties on both sides. Vietnam on the other hand.... we shouldn't have been there in the first place.
I define myself as an aggressive isolationist, but a defender of people in every day life. If fighting can be reasonably avoided, like Korea, Vietnam, Iraq, then don't fight. And if all possible, just totally stay out of other countries affairs. However, if we are attacked, like in WWI and WWII, fight with every ounce of strength. Hit the enemy at every good chance. Defeat them as quickly and violently as militarily appropriate so that they are defeated sooner, and so others see and think twice about attacking us. But in every day life, I'll fight anyone who is attacking another person. I don't care if the person being attacked is an ex murderer. If he/she is being wrongly attacked, I'll defend them. However, I try to not start fights, and keep them from getting to that stage.
