War is sometimes necessary, and is also a fact of life. It's not pretty, but sometimes it's the only way.
I don't think war is ever necessary. If two countries have a disagreement, they should just negotiate in a mature way.
I especially think the war in Iraq is really dumb. The US has no right to tell other countries what to do.
If we tried that on Hitler and the Japanese instead of fighting and defeating them, the world might be completely under a single dictatorial rule, and commanded by Germany, Italy and Japan. You can't negotiate with some people - because some people believe they are beyond normal rules and have the right to rule other other countries. Just look at people like Robert Mugabe, Hugo Chavez, and Kim Jong II. Do you honestly think that negotiation with these scum is going to stop them from killing their own people and destroying their countries for the pursuit of military strength and domination?
In fact, I think this whole "war on terror" is just an excuse to take away our rights (and to take the Arabs' oil). I believe that the government either planned or allowed the events of 9/11 to happen just so they'd have an excuse to start wars and do stupid stuff like the Patriot Act.
Oh no, don't get started on conspiracy theories. There is almost no evidence whatsoever that the US themselves did this, and many Muslim prisoners of war have already testified to planning these attacks for the purpose of Jihad. Personally, I think people usually believe this junk just because they want to blame everything on their leaders, as always. It's always the President's fault - the US has no enemies but the ones that are only trying to defend themselves from the insidious rule of Bush the Tyrant. I can't stand stuff like that.
Note: Please realize that the above is my opion as well, and I am not trying to insult anyone in this topic. Thank you.
