As we've said so many times before, things can always get worse.

From The Guardian ...

Turkey and Iran have dispatched tanks, artillery and thousands of troops to their frontiers with Iraq during the past few weeks in what appears to be a coordinated effort to disrupt the activities of Kurdish rebel bases.

Scores of Kurds have fled their homes in the northern frontier region after four days of shelling by the Iranian army. Local officials said Turkey had also fired a number of shells into Iraqi territory.

Frustrated by the reluctance of the US and the government in Baghdad to crack down on the PKK bases inside Iraq, Turkish generals have hinted they are considering a large-scale military operation across the border. They are said to be sharing intelligence about Kurdish rebel movements with their Iranian counterparts.

The Israelis have deep ties to the Kurds. And they'd probably like to help them tangle with the Iranians. But Israel also has a key alliance with Turkey. So that might present some problems. David Frum thinks we should withdraw to the Kurdish north and make our stand there too. So Kurdistan should be a lot of fun for everyone.
