Obama and Iraq/Pakistan/Afghanistan - help me understand this before my primary

[Riley133]

OK, I've been reading the posts begging people to 'get over it' and pick a candidate already. I've made a pouty, snarky remark myself recently so since I was guilty as charged, I decided to try to figure out which of the two frontrunners I would like to vote for, which leads me to this:

In Senator Obama's remarks linked here

http://www.barackobama.com/2007/08/01/remarks_of_senator_obama_the_w_1.php

he advises getting out of Iraq but expanding into Afghanistan and Pakistan.

These remarks are dated August, 2007. Please enlighten me on this - it seems the people I talk to who are Obama supporters are convinced we're just going to walk right out of the ME, but I don't see it. What's changed that I don't know? What am I missing here?

My apologies if this has been hashed out before.
