As for how Turkey might respond, Jack has a fascinating post: The Infidel Turk which argues that al Qaeda may have awoken yet another sleeping giant.

Jack (and David Warren) make some very valid points, and factor in both geography and the Turkish army. The Turkish army considers itself to be the guardian of modern Turkey and is the most powerful army in the Mid-East.

In a Washington Times commentary, Claude Salhani, senior editor with UPI, gives a brief run down on how Turkey has dealt with terrorism in the past, and says the al Qaeda attacks in Turkey guarantee that the gloves will come off.

According to an AP dispatch, Turkish Prime Minister Recep Tayyip Erdogan spoke to Israeli PM Sharon by phone and the two have pledged cooperation in fighting terrorism:

Erdogan spoke on Saturday with Israeli Prime Minister Ariel Sharon by telephone, agreeing to cooperate in the fight on terrorism. The chief of Israel's Mossad secret service agency reportedly traveled to Turkey this week following the attacks in an apparent expansion of coordination between the allies.

Turkey and Israel have built up strong military and trade ties. Now Turkey is seeking Israel's expertise from more than 100 suicide bombings since September 2000 and knowledge on how to track Islamic militants.

Neither Syria nor Iran have been hit by al Qaeda, and implications are easy to draw yet hard to prove. I don't know if actual war could erupt, but Turkey is reviewing its list of terror cells, and a demonstration yesterday indicates the Turkish people are not going to allow terrorists to intimidate them or deter them from maintaining a secular government.
