Cynicism and the political instrumentalization of 'genocide'

I agree with Joshua Keating's conclusion to his post on the political intrumentalization of the Armenian genocide by American politicians:

All in all, the level of cynicism in Washington around this tragic historical event  is pretty disheartening. Like President Bush before him, President Obama was for using the word "genocide" as a candidate before he was against it as president. Former House Majority leader Dick Gephart, who supported recognition as a congressman, is now lobbying against it on the Turkish payroll.
Outside the Armenian-American community, whose grievance on this issue is understandable and shouldn't be dismissed, most Americans would probably prefer that the congress focus its efforts on preventing and ending current conflicts.

France passed a law recognizing the Armenian genocide in 2006 and it just gave politicians an occasion to grandstand or to argue that Turkey didn't have its place within the European Union for it was made much news since or has no impact neither in France or in Europe on the important questions. The argument is that genocide should be something politicians play football will and that only historians ought to write history.
