I'm not seeing what it has to do with domestic policy. I really don't think any politician in the United States is so hard up for the Turkish-American vote that they'd actively get in Congress' way of passing a "Tsk, tsk" resolution. And I bet that, had anyone tried to pass a resolution in Congress that denounced Israeli wrongdoings, the Bush and Obama administrations would have gotten in the way of that, too.
And it's 100% a foreign policy matter.
From Incirlik Air Force Base's Wikipedia page:
On 19 August 2003, the first rotation of deployed KC-135 Stratotankers and airmen arrived at Incirlik to support various operations in response to the 11 September 2001 attacks as well as the post-invasion reconstruction of Iraq and the ensuing insurgency.
On 6 January 2004, more than 300 soldiers of what would become thousands transited through Incirlik as the first stop back to their home post, after spending almost a year in Iraq. Incirlik was part of what was described as the largest troop movement in U.S. history. Incirlik provided soldiers with a cot, warm location, entertainment and food for a few hours outside of a hostile war zone.
On 12 March 2004, the 39th Air Base Group deactivated, and the 39th Air Base Wing activated to provide the best mix of required support and, as new mission requirements emerge, to shoulder the burden and better contribute in the global war on terrorism.
And speaking of Israel, if the US Government decides to kick Turkey, not only will the Turkish Government probably be pissed enough to kick us off their air force base, but the Turkish populace might just be irked, too, becuase we're mostly mum on Israel's wrongdoings of a year ago, let alone a century ago. And they might be inclined not to give us a friendly Turkish Government for a while.
