It's easy to get wrapped up in al-Zarqwai's death. It's even easier to view this as a massive turning point in the Iraq war. I like to believe that it is a turning point, and that sectarian violence is going to decrease.
What has happened here is surely a victory for America. However, this can easily turn into a momentum swing for al qaeda. It has been said that al-Zarqwai's role was inflated by the US. There had to be a scapegoat for the sectarian violence in Iraq, and Zarqwai was made that man. It's also easier for the US public to support something when there is a clear goal (i.e. eliminate Zarqwai).
I don't want to undermine what has happened here, because I do feel like this is a monumentous event for our troops. But, let us not forget that al qaeda thrives on martyrdom. Al-Zarqwai has been made a martyr, and sometimes that makes the deceased individual even stronger. Also, on many occassions, it has been proven that these qaeda operatives can still be effective, if not stronger, without leadership.
So, lets go ahead and celebrate what has gone on here because it is surely a day of triumph. But, we have to make sure not forget who our enemies are, and what they are capable of.
