Ruffling feathers - will Turkey invade northern Iraq?

Turkey is once again undergoing preparations for a possible invasion of northern Iraq to disrupt the activities of the Workers' Party of Kurdistan (Partiya Karkaren Kurdistan: PKK). On 7 August, Iraqi and Turkish Prime Ministers Nouri al-Maliki and Recep Tayyip Erdogan signed a Memorandum of Understanding to jointly work towards ending the PKK presence in Iraq. The decision followed Turkey's July general election, won by the ruling Justice and Development Party (Adalet ve Kalkinma Partisi: AKP), which saw the opposition parties, the Republican People's Party and the National Action Party, running on nationalist platforms.

Such a cross-border operation against the PKK would not be unprecendented. Turkish soldiers have been fighting the PKK in Iraqi Kurdish regions since the mid-1990s, usually just across the border from Turkey. Every few years the fight against the guerrilla movement reaches a minor crescendo, with the Turkish military weighing the option of swooping into the Kandil mountains to completely destroy the PKK's camps. Four significant incursions were launched in the 1990s and 2001.

So far, Turkish deployments inside Iraq have been modest. Kurdistan Regional Government (KRG) Prime Minister Nechirvan Barzani (nephew of KRG President Massoud Barzani) confirmed in early August that Turkish troops had already begun operating in Iraqi territory. However, their main activity has consisted of preparatory work on the Turkish side of the border, in particular the establishment of 'temporary security zones' in the border provinces of Hakkari, Siirt, and Sirnak. These zones involve tighter controls on civilian movement and could be a prelude to cross-border action.

As these zones and the election demonstrate, attacking the PKK camps is once again being considered seriously in Ankara. Perhaps the most significant reason for this is that the PKK's insurgency has shown surprising resilience by sustaining itself since ending its unilateral ceasefire in May 2004, and there are signs it has taken lethal new tactical turns. In addition, given the PKK's strategic reliance on static camps, the military is confident that it could deal a substantial blow to the organisation in a cross-border operation.

Domestic factors also provide a favourable climate for an invasion in 2007, particularly the ruling AKP's desire to demonstrate its Kemalist credentials. The party narrowly failed to win the two thirds of parliamentary seats necessary to act unilaterally in appointing a president, and so it needs to pander to nationalists such as the National Action Party. Also, a stand-off between the military and the government in May, when the armed forces all but threatened a coup if the AKP's preferred presidential candidate was appointed, demonstrated that the AKP must also take into account the military's wishes in its appointments and policies. An invasion to tackle the PKK is supported within the military and could be seen as a concession to the armed forces from the AKP.
