No one. The Communists have never been in power in the US. There has also never been a coup in the US.
If you are an ambassador stationed in the country where the coup occurs, you would call your superior and find out what to do regarding evacuation of yourself and other members of the embassy. If you represent a country where the coup occurred, you wait and see about the outcome. Theoretically, you could be recalled, sent to the president (if you are in the US) with messages, jailed, or, ignored while the coup occurs.

It is very hard to imagine a successful military coup in the U.K. Even when the country suffered from a weak economy (in the late 1960s and also in the mid 1970s) there was no coup. There were stories to the effect that some people had talked in terms of a coup, but there is no real evidence. A coup can usually only succeed if the civil service and others are prepared to co-operate.
Absolutism, which emphasizes the absolute authority of a ruler, could justify a coup d'état by arguing that the existing government has failed to fulfill its divine or natural mandate to govern effectively. Supporters of a coup might claim that the ruler's actions are illegitimate or tyrannical, thus justifying their removal in order to restore order and the rightful governance that benefits the state. Additionally, proponents could argue that a strong, centralized authority is necessary to maintain stability, and a coup could be framed as a means to achieve that end.
The military coup could have been averted with discreet diplomacy.The Native Americans' Plains tribes highly regarded 'counting coup' was more important than the taking of the enemies' lives.The very first British Airborne assault on Pegasus Bridge in the Battle of Normandy is a classic example of a coup de mainoperation.
