bluff
Their bluff-as you call it- was a direct challenge calling our bluff. So, what do you propose we do? Overt action, diplomacy, or send in Madonna?
"We call there bluff" is not an answer unless you propose how we do that.
My larger question is how does the US deal with the rest of the world? Should we be bullys or buddies? And how do you propose we do that?
