I remember when Turkey wanted to invade the northern part of Iraq because the Iraqi Kurds there were suspected of harboring the Kurdish separatist group PKK, which was involved in terror activities inside turkey in the past, the US was urging Turkey not to do it, because it might destabilize Iraq.
Fast forward to July 2008. Afghanistan is becoming more violent because the Al queda types who are based in the northwest frontier province of Pakistan are making more frequent attacks on Coalition forces and Afghan targets, then retreating back to their sanctuary inside Pakistan. The Afghan military and the US Coalition forces want to pursue al qaeda inside Pakistan territory (Waziristan) to destroy their bases there.
Kinda like Turkey's pursuit of PKK terror groups inside Iraq, no?
