MJDuncan,
If you'll humor me, I'd like to respond to your question with another question.
Do you really think that capturing Osama Bin Laden is going to change anything?
Some people are unconcerned with OBL because he has fallen out of the media spotlight, and their attention spans are that short. Many, myself included, do not continue to harp on OBL because we know a number of things.
1) If he is not dead already, he IS being searched for relentlessly. OBL's caputre would be a HUGE BOON for Bush, even the most cynical liberal has to admit that It would be GREAT for Bush if OBL was captured, so there is no reason for Bush NOT to be searching for him.
2) Capturing OBL, while fufilling some emotional need we have to "catch the guy behind 9-11" does not finish anything, it does not signal the end to the War on Terror, it does not mean that terrorism will stop...all it means is that we caught one of the terrorists, albeit an important one.
People who are unconcerned with OBL's capture understand that to make the world safer, the world has to change.
Capturing one man is not going to make that change happen, no...for this change to happen an entire area of the world, if not the entire world, has to change...terrorists have to be caught (including OBL)...but more importantly, nations who encourage, support, and hide terrorists must be dealt with (not always be war, but they must be dealt with)...nations living under tyranny must be given the opportunity to flourish under freedom, whatever form of it they choose isn't our responsibility...but giving them the ability to do so is something that will benefit us immensely...nations and powerful individuals who made money from dealing with terrorists and dictators need to know that that behavior will not be acceptable in this new changed world...that the US will not follow the advice and instructions of "friends" who are backstabbing us while they smile and talk about morals....the UN needs to act rather than write strongly worded letters to insane madmen who laugh at them...etc etc etc.
OBL is still hated, everyone still wants him to be found. But I think the reason why conservatives, Bush, and people who support Bush are not screeching for him to be the only priority is because we understand that thinking catching one man is going to change anything is small-minded, and represents a complete lack of understanding on the big picture of global terrorism and how we can begin to destroy it... (hence, the big reason why I will not be voting for Kerry...I do not think he understands this)...
Bush (or at the very least, the people around Bush) understands that we are not dealing with OBL alone...we are dealing with GLOBAL terrorism. Catching OBL will be a wonderful thing for the US, but it will not be the end of the problem...
In my opinion, Bush is looking at the big picture - how to take the first steps towards a world without terrorism...create a world in which terrorism no longer thrives. Kerry is planning on taking on terrorists one at a time...OBL plans 9-11, catch him. Someone else blows up a school, catch them. Someone nukes Chicago, catch them. Kerry feels that terrorism will never go away...Bush thinks that it can...but it isn't going to happen soon, and it isn't going to happen easily...and it isn't going to happen, even if the entire US military is looking for OBL.
