The war of the stubborns

At one point, the US authorizes Z. Khalilzad to talk to Iranian officials on Iraq's security issues. At a later time, when Iran's supreme leader says OK, the US administration questions the OK:

Administration Questions Iran's Motives:
The Bush administration questioned on Wednesday the motives of Iran's Supreme leader Ayatollah Ali Khamenei in approving U.S.-proposed talks on Iraq, but did not shut the door entirely.

And then the reason behind the suspicion is stated as:

"It is a matter of curious timing," State Department spokesman Sean McCormack said, suggesting Iran was trying to deflect international pressure from its nuclear programs now under criticial discussion at the United Nations.

I personally think it is the other way around. US has always been accusing Iran of supporting insurgencies in Iraq. Suddenly, it is said that Iraq's stability is not possible without Iran's involvement and the US decides to get involved in talks with Iran. How odd it is to talk to someone who is your enemy! Now, who is deflecting international attention?
Whatever the reason, I am glad that both parties are moving in the direction that they should. I am hopeful that it'd open up more doors rather shutting doors up.
