It is a classic case of the old saying, “Do as I do and not what I say”.
Political rhetoric is a tricky art.
Reading it or analyzing what it actually means can be a challenge to the uninitiated.
Therefore, all parties must exercise reasonable restraint in responding to such highly emotional and partisan outbursts.
Washington said Manila had not officially communicated President Duterte's demand to pull US military advisers out of the rebellion-torn southern Philippines.
Since 2002, up to 600 US advisers have been deployed in the Mindanao region to train troops battling Muslim extremists, but their numbers have been scaled down in recent years.
A week after calling US President Barack Obama a "son of a whore", the incendiary leader said Monday US Special Forces in the region "have to go".
Foreign Secretary Perfecto Yasay however attempted to downplay Duterte's comments, saying Tuesday they were "in the context of wanting to save the lives of these Americans who might be exposing themselves to unnecessary risk" from militant attacks.
See what we mean?
In Washington, the Pentagon and State Department said they had not been officially contacted by Manila about pulling out the remaining advisers.
Yasay also confirmed the allies had not discussed Duterte's demand.
He said only around 100 US advisers were left in the south of the country.
The Pentagon in June also deployed warplanes and about 120 personnel in the northern Philippines for short-term training missions aimed at ensuring the allies' access to the disputed South China Sea.
Duterte, 71, has said he is "not a fan" of the United States and on Monday explained his demand by showing pictures of US troops killing Muslims as America took control of its new colony in the early 1900s.
He has said the spat was triggered by State Department criticism of his controversial war on drug crime, which has left about 3,000 people dead since he began his six-year term on June 30.
Obama has said Duterte must conduct his crime war "the right way", protecting human rights.
Yasay stressed that Duterte's new comments did not signal a shift in policy, and that ties with the US remained strong.
The president only wanted to protect Americans from kidnappings and terrorism as they had become "a very good target", Yasay said.
"There is no shift in so far as our policy is concerned with respect to our close friendship with the Americans."
Yasay, who was heading to Washington for talks, added the Duterte administration would honor existing defense agreements including a 2014 accord giving the US military access to at least five Philippine bases, one of them in Mindanao.
However analysts said any drawdown could come at a time of deteriorating security in Mindanao, with the presence of extremist and splinter rebel groups, some of which pledged allegiance to the Islamic State group.
Zachary Abuza, a Southeast Asian security expert at the National War College in the United States, said Duterte's actions towards the US were worrying.
"National security professionals that I am in contact with are agog with the behavior of a treaty ally," Abuza told AFP.
