I actually agree with you in that Bush could be doing a better job as President of the United States but I disagree with you in that going into Iraq was a mistake. In my opinion, he was honestly attempting to make the living conditions for people being treated like slaves under a tyrant leader better, whether they wanted his help or not. I'm also willing to bet that the people who were rooting for Sadam were Iraqis who either:
A) ...took Sadam's side out of fear for their lives. The common man.
B) ...felt the need to aid the person who had them in a position where they were corrupting the government for their own personal gain. In other words, greedy, evil bastards.
...and with Sadam having control over Iraq's oil as well as a royally self-centered thirst for power and complete obedience from his rivals, he may have risen to be an even greater threat to the US(and the rest of the world) had we not taken him out when we did.
I'd also like to add that the people preaching that we should end the war in Iraq appear to me to be selfish. They're only thinking of themselves and how they feel, never even glancing outside of the perfect little make-believe world that they've constructed within their own mindset. Think of how the Iraqi people were constantly living in fear of the very person who was supposed to protect them. Sure, those flaming liberals may miss their loved ones but it's all a part of war and joining the military. Some things are necessary such as sacrificing time spent with your family for the betterment of the world. If we were to pull out of Iraq and send all of our soldiers home, the surviving insurgent camps would simply run right back in and take the country over again and we'd see another evil idiot rise to power. The process would just start over. It would be like giving up the race before seeing the finish line.
But I agree, Bush may not be the best guy for the job. He could have done so much more with the time he spent in office, in my opinion. But I think that his decision to go to war was made with the absolute best intentions.
To anyone that I may have offended:
P.S. The fact that you're 13 years old gives me hope for America's youth.
