Samantha Power.

When Irish Eyes Are Flashing, sure 'tis like A Prob from Hell.
In the flash of Irish temper, you can see diplom'cy's knell.
When Irish hearts are racing, all the world seems glum and gray,
And When Irish Eyes Are Flashing, sure, 'tis time to drag her away.

Ambassador Power, long-time friend of President Obama's, is, evidently, a passionate individual, a devoted FoB. Her embarrassing lash-out at Ambassador Churkin was not her first lash. She was a senior adviser to candidate-Obama when, at a crisis point in the 2008 campaign, she gave Hillary Clinton a taste of the lash:

"She is a monster, too--that is off the record--she is stooping to anything. You just look at her and think, 'Ergh.'" http://www.scotsman.com/news/hillary-clinton-s-a-monster-obama-aide-blurts-out-attack-in-scotsman-interview-1-1158300 She had to resign after that.

"Ambassador" Samantha Power. Ambassador! Sounds like a perfect position for her, no? 

A belated Happy St. Patrick's Day...Ambassador.
