Calling someone's logic flawed can be misinterpreted as a personal insult.
That being said, conflict exists everywhere there are animals. The bulls fight over grazing land and cows to boink, dogs fight over leadership and can outcast each other under threat of death, and bees fight to kill the other queen. In my opinion the weapons of war are much deadlier then before, but war itself seems less deadly then ever. We have the Geneva Convention and other treaties to thank for that. Your chance of surviving nowadays is much higher then it used to be due to the outlaw of exploding bullets, gas, and flame-throwers. Also, there is compelling evidence that the West has taken extra steps to care for the enemy wounded more then ever.
Tragedy happens, but in democracy, when you send your young men and women into war, it's your war too. The troops don't send themselves, the civilians do.
