Officials in Washington are saying that if Pyongyang launches anything that threatens the territory of the US or its allies, it will be shot down.
North Korea has not explicitly said it will conduct an ICBM test in the immediate future, and it is safe to assume US policy has always been to shoot down any missiles that threaten its territory.
But the recent barb trading could suggest Pyongyang and Washington are feeling each other out ahead of President-elect Trump's inauguration on January 20.
Trump himself responded with a tweet two days later, saying the possibility of the North developing a nuclear weapon capable of reaching the US "won't happen!"

Upping the ante, the state's KCNA news agency quoted a North Korean Foreign Ministry spokesman as saying yesterday that Pyongyang reserves the right to conduct a test whenever it sees fit.
Also yesterday, on "Meet the Press," US Defense Secretary Ash Carter called the North's missile and nuclear weapons development a "serious threat." .
He said the US military would shoot down any missiles launched by the North that appeared to be headed toward American territory or the territory of any US allies.
Beyond the rhetoric, however, the KCNA report suggested Pyongyang is hoping Trump will take a new approach toward relations.
The KCNA report slammed US Deputy Secretary of State Anthony Blinken for saying last week that sanctions must be maintained to keep the pressure on Pyongyang.
"Anyone who wants to deal with the DPRK would be well advised to secure a new way of thinking after having a clear understanding of it," KCNA quoted the foreign ministry official as saying.
