Two issues are currently occupying a great deal of public attention in Turkey: the Armenian genocide resolution in the US Congress, and PKK activity in southeastern Turkey and northern Iraq. While the former has also received significant press coverage in the US, there seems to be very little awareness in the American and European media about the latter. For the Turks, the lack of concern shown by the Europeans and the Americans for the dangers posed to the country by PKK attacks is a source of deep frustration and a sense of abandonment. People in the government and the press are openly questioning the value of Turkey's partnership with America and the West. Indeed, many are implicating the US in the terrorist attacks by the PKK, referring repeatedly to the alleged discovery of American weapons in PKK hands. The Armenian genocide resolution seems to these critics of the US yet another indication of America's evil intentions (or, at best, indifference) with respect to Turkey. Rather than interpreting the genocide resolution as a product of America's democratic culture, the Turks seem to be reading it as another example of Western hypocrisy and imperialist interference in Turkish affairs. Furthermore, it is hard to ignore the thinly-veiled expressions of anger at "the Jewish lobby," which some Turkish commentators are now depicting as part of an anti-Turkish alliance with "the Armenians."
There is very little that the Turks can do to directly influence Congress at this stage. The White House's furious diplomatic activity against passage of the House resolution to recognize the Armenian genocide seems doomed to failure. Likewise, Turkey's power to take direct action against either the Iraqi Kurdish government or the PKK is also somewhat limited. This does not mean that the Turks will be able to hold off indefinitely public opinion calling for some kind of response. But it seems that the Turkish military and government realize the risks and difficulties of a more extended cross-border operation. Economic sanctions against the Iraqi Kurds are also a possibility - but they may also hurt Turkish interests in the area.
This leaves Turkey with a more indirect option. While the Turks have been thwarted in their attempts to project direct military force in the region (mainly because of the presence of the Americans), they do have the ability to disrupt significantly American strategic aims with respect to Iran and Russia. Turkey is the key to two planks of American energy policy: 1) to isolate Iran, and 2) to provide an alternative to Europe-bound Russian oil and gas pipelines.
The Americans have been watching Turco-Iranian energy cooperation with a great deal of concern. But the lack of American concern for Turkish interests in Iraq, has pushed the country to drop its inhibitions about upsetting the Americans on this front. Indeed, some Turkish politicians seem to be advocating cooperation with the Iranians on the Kurdish issue as well. As for Russia, despite Turkey's investment in American-backed infrastructure projects in the South Caucasus, the Turks have no qualms about serving as another gate for Gazprom energy to Europe and the Levant. The more the merrier.
