Sinsull et al.--

It's clear from the articles you cite that Brown is hedging his bets. It's not at all clear that all UK troops will be leaving Iraq soon----"Brown has...refused to announce a timetable for the complete withdrawal of UK troops from Iraq"-----or ever. So no change there.

You posit a false choice. The US can stay in "Kurdistan" indefinitely without fighting the PKK or the Turks--as long as PKK provocations don't cause a full-scale invasion by Turkey. And the very presence of US troops in "Kurdistan" is likely to deter an invasion. This is very clear to Kurds in "Kurdistan".
