According to the article below, what does the US want? Nuclear Fuel Memos Expose Wary Dance With Pakistan on new york times

There are a number of things that the United States wants
from Pakistan that are discussed in this article.  I will mention what I think are the
two most important.

First of all, the title of the article
talks about nuclear fuel.  This is an important issue.  Pakistan has a nuclear program. 
The United States is very worried that nuclear fuel that is produced by the program
might make its way into the hands of terrorists.  This could be used to make a "dirty
bomb."

The other major thing that the US wants is
cooperation from Pakistan in the fight against terrorism.  The US is concerned about A)
Pakistan giving support to the Taliban in Afghanistan and B) Taliban and Al Qaeda
members hiding out in parts of Pakistan that the government cannot really control.  The
US wants Pakistan to crack down on both A and B.
