What's it good for?

I thought far too hard and for far too long about how I was going to answer this blog post. I don't want to be the inevitable stickler who seems to answer without thinking that of course there is no time for war.
Even if that's initially what I wanted to write.
Essentially, I think it's rather stupid and pointless to determine a "winner" by sending people to die and counting the last people standing, granting the victory to those with the most people left. The thing is that so many people die, and so many families feel that pain, and even if someone doesn't die, they still come home scarred with horrors of war. It honestly seems to me that nothing really good comes from war--people die, and people come back practically dead, and there's a winner and a loser. And that's all.
It is actually really hard to write this, but I think that at this point, war is sometimes necessary, but it shouldn't be. In other words, if we as a nation let others attack and walk all over us, we would all suffer; fighting back is natural there. What's messed up is that we actually do have to worry about that. If respect for other people were a universal concept, maybe we wouldn't have to worry about war. If there weren't groups that made it their job to hate, then no one would have to fight back.
Reading back on that, I am still arguing with myself and I'm tempted to just write NO I TAKE IT BACK I TAKE IT BACK! It seems that people can always negotiate instead of just killing each other.
I am trying so hard to look at both sides, I promise! I think all I did here was just confuse myself even further though. Maybe I should stop writing now.
