Why Can't I find Obama's Master's Thesis?

Go ahead, give it a shot. Google "Barack Obama Thesis." You'll get plenty of hits on Michelle Obama's thesis or Michelle LaVaughn Robinson , but very little on Barack's thesis. By the way, you should check out Michelle's piece of work. Princeton won't officially release the document until after the election, but you can easily obtain a copy online by clicking here.
What is known about Baracks masters thesis from Columbia University is the title "Soviet Nuclear Disarmament" and that Columbia will not release it and doesn't plan to in the future. What else is known? Barrack was attending communist rallies and involved in Marxist ideals around the time he was writing his thesis.

If this doesn't concern you, you're an irresponsible voter and should stay home on November 4th. This man is applying for the most powerful job in the world and is not willing to release his complete references. Let me be clear on this, it's like interviewing someone for a job and the candidate telling the hiring supervisor "you aren't allowed to check my references". You would be buffoon to hire the person.

This leads to the following questions:
Why is his thesis so hard to find?
What is he trying to hide?
What is Columbia University trying to hide?
What are is true ideals and motivations?
Why is there such a hedge of protection planted by Obama'a campaign, Columbia and the Media around this issue?

It looks like the press is not going to ask him about his thesis work so I would assume the worst.

P.S. For those of you who do not know what a thesis is, it's basically your graduate work culminated into a big paper. Its a big deal and takes a tremendous amount of time, effort and work. You are passionate about your thesis and that's why you usually have to defend your thesis by answering a barrage of questions from your peers and professors to graduate.

Update:
I emailed the Obama campaign about this and their response was to direct me to a couple of websites that defend/debunk the smears the right wingers are making about him.

However to no surprise I did not find any information on Obama's thesis work and snopes.com infected my pc with spyware.
