Why now?

The Congress is pushing this resolution condemning the Turkish genocide of Armenians. While this should not be ignored by history, my question is: why now???? This is not exactly recent history as it happened from 1915 to 1918. Turkey has it's problems, but is an ally and friend. Why does Congress want to poke her with a stick? Closing down the airbases in Turkey will definitely hinder operations in Iraq. If we are to withdraw from Iraq, let us do it on our terms and not be forced to by an uncooperative neighbor.
