Following Kim Jong-Un's televized response to Trump's UN speech, in which he called the US president a "mentally deranged dotard" and vowed to "tame the U. S. dotard with fire", Donald Trump took to twitter this morning, responding in kind that "Kim Jong Un of North Korea, who is obviously a madman who doesn't mind starving or killing his people, will be tested like never before!"

As a reminder, Kim's last jawboning effort deserved a solid A+ for vivid tragicomic imagery and hollow threats:

"[Trump's] remarks remind me of such words as "political layman" and "political heretic" which were in vogue in reference to Trump during his presidential election campaign." The mentally deranged behavior of the U.S. president openly expressing on the UN arena the unethical will to "totally destroy" a sovereign state, beyond the boundary of threats of regime change or overturn of social system, makes even those with normal thinking faculty think about discretion and composure. "After taking office Trump has rendered the world restless through threats and blackmail against all countries in the world. He is unfit to hold the prerogative of supreme command of a country, and he is surely a rogue and a gangster fond of playing with fire, rather than a politician." "I am now thinking hard about what response he could have expected when he allowed such eccentric words to trip off his tongue. Whatever Trump might have expected, he will face results beyond his expectation. I will surely and definitely tame the mentally deranged U. S. dotard with fire."

The latest war of words, which also prompted North Korea to threaten another hydrogen bomb test overnight, erupted after Trump signed an executive order on Thursday that would slap sanctions on individuals, companies and financial institutions that do business with North Korea, or as Trump called the nation “this criminal rogue regime.” He said his mission was North Korea’s “complete denuclearization.” Also earlier this month, the U.N. Security Council passed harsh sanctions on Kim's small nation, as it continued to fire threatening missile tests and claim the expansion of its nuclear arsenal. The sanctions ban 90 percent of North Korean exports and were approved by Russia and China, who had previously maintained closer ties to North Korea.

In a separate tweet, Trump also warned that any Republican lawmaker who votes against the new Senate GOP ObamaCare repeal bill will be known in "future political campaigns" as "the Republican who saved ObamaCare."

"Rand Paul, or whoever votes against Hcare Bill, will forever (future political campaigns) be known as "the Republican who saved ObamaCare."

Paul has firmly opposed the new ObamaCare repeal measure put forward by Sens. Lindsey Graham (R-S.C.) and Bill Cassidy (R-La.). Paul on Tuesday criticized the new Senate GOP ObamaCare repeal bill as a "government boondoggle of a trillion dollars." The measure would repeal much of ObamaCare by converting funds for certain provisions into block grants to states. Eyes are also on Sens. John McCain (Ariz.), Susan Collins (Maine) and Lisa Murkowski (Alaska) who voted against the last ObamaCare repeal measure and who have yet to say whether they would vote in favor of the Graham-Cassidy bill.

Trump has railed against Republican lawmakers for failing to repeal ObamaCare, a longstanding GOP promise, despite having a majority in both chambers of Congress. The president set his sights on Paul earlier this week, calling him a "negative force" in similar tweets early Thursday. "Rand Paul is a friend of mine but he is such a negative force when it comes to fixing healthcare. Graham-Cassidy Bill is GREAT! Ends Ocare!" he tweeted.

"I hope Republican Senators will vote for Graham-Cassidy and fulfill their promise to Repeal & Replace ObamaCare. Money direct to States!"
