That tweet irritates me. It doesn't make any sense. What King killed people at the red wedding? The only king there was the one getting stabbed. And none of the murdering at the Red Wedding required or featured any substantial display of 'balls'. It was actually quite a cowardly act. You would think an editor at a prestigious (I'm assuming from the article - I've never read TNR) magazine would either be aware of what actually happened in the fictional event he is referencing or be above shoehorning in pop culture references for their own sake.
