General H. R. McMaster fired the threat at Kim Jong-un after the despot reminded the USA that the “nuclear button is always on my desk”.
The National Security Advisor said: “If sanctions don’t work what we have to do is prepare for a broad range of options for the President.
“And those include military options, and we’ve made no secret about that.”
