They usually do it behind closed doors.

Remember in 2006 when the Pakistan President revealed that top U.S. officials threatened to "bomb Pakistan back to the Stone Age" after 9-11?

No, they didn't tweet it out and tell everyone...but YES our country has ALWAYS threatened and taunted.
That's all part of arguments, negotiations, etc.

In the end...all these diplomats are just: People.
They aren't geniuses. They aren't some kind of infallible super-men and women.

Threats are made all the time. At the U.S. and by the U.S.

You just are getting a President that doesn't hide shit from the American people anymore and we aren't used to seeing the truth.
We have gotten used to being lied to by govt. and placated to FEEL "safe".

EDIT:
Here's a quick history lesson:
"In 1953, Eisenhower threatened the use of nuclear weapons to end the Korean War if the Chinese refused to negotiate.

The United States issued several nuclear threats against the People's Republic of China in the 1950s to force the evacuation of outlying islands and the cessation of attacks against Quemoy and Matsu, part of Republic of China.

Recently declassified documents from the National Archives (UK) indicate that the United Kingdom considered threatening China with nuclear retaliation in 1961 in the case of a military reclamation of Hong Kong by China.
Ali Magoudi, a psychoanalyst of French president François Mitterrand, claimed that Margaret Thatcher threatened nuclear war against Argentina during the 1982 Falklands War in order to procure codes from France to disable Argentina's French-made missiles. This claim has not been confirmed by either the French or British governments.

In 1981, the United States Department of Energy said there had been 75 cases of nuclear blackmail against the United States, though only several were serious attempts."
