For the answer simply read the story.
There are many in the United States, I'm sorry to say, who are so intent upon seeing Bush humiliated that they are more closely allied with Al-Qaeda in Iraq then they are with the decent people of Iraq. Oh, I know they wouldn't want to put it that way, I know they aren't actually in favor of the atrocities being committed by the Jihadists, but truth be told they need Al-Qaeda to keep committing those atrocities.
If the insurgents are defeated that means that Bush will have been victorious, that he will be seen as a winner. That is something the left simply cannot tolerate. The left is deeply, deeply invested in the United States failing in Iraq. Iraq is their Vietnam, their holy grail. It is their chance, as they see it, to regain the power and influence they had directly following their victory (our loss) in Vietnam.
I honestly don't know if Bush did the right thing by going into Iraq. I have privately struggled for years with that issue. I can certainly say that I have disagreed with Bush about many things, most especially his stance on Illegal Immigration. But something had to be done, and many things still must be done, in our struggle against radicalized Islam and Terrorism. This was laid on our doorstep, we did not ask for it.
Have we made mistakes in the past? Yes. Will we make mistakes in the future? Yes. Do we just roll over and give up because things are hard? No! We deserve better, this world deserves better, than to be led by the weak into the jaws of the lion. One thing Bush and Blair will never have to worry about is being called weak. At least when it comes to their leadership in the fight against Terrorism.
The war being waged by the radical Islamists is a fight to the death. That much anyone who looks honestly at the situation can see. It doesn't much matter what we do or say, they have vowed to destroy us and our way of life. Pretending the danger doesn't exist won't make it go away. Trying to appease those who hate our very existence won't make any difference. We either fight them now, in Iraq, or we fight them somewhere else. War has been waged against us. Our options have been taken away. Peace, as much as we desire it, is not in the cards for quite some time.
Now is the time for the land of the free and the home of the brave to defend its freedom and prove its bravery. Yes, we've been sissified by years of feminism and other liberal dreck, but we haven't been completely emasculated. Not yet anyway.
