I apologize. Obama does not threaten; he promises. He doesn't live up to his promises, but he will call you. One of these days. If he hasn't lost your number.
In the case of Putin bitch-slapping the president yet again (first on Syria, and now Ukraine), the consequence was on Obama. Except he dodged everything to go to a film festival.

A president certainly may pick and choose which meetings to attend, but skipping stuff when his diplomatic history is at stake and then to go all badass on “There will be consequences …” Well, badass looks more and more like dumbass.
