Republican Senator Bob Corker is worried that President Trump is “reckless enough to stumble [sic] the country into a nuclear war.” This from the two War Parties who’ve not stopped egging Trump on about Russia, fomenting American aggression against that potential partner. The president wanted—was willing—to make peace with Russian; the UniParty would have none of it. Now DemoPublicans are worried.

President Trump has failed miserably in forging forward with peace vis-a-vis Russia and sending out competent spokespersons to explain that campaign promise and the attendant policy of diplomacy and American First.

… Senator Bob Corker, the Republican chairman of the Senate Foreign Relations Committee, charged in an interview on Sunday that President Trump was treating his office like “a reality show,” with reckless threats toward other countries that could set the nation “on the path to World War III.”

In an extraordinary rebuke of a president of his own party, Mr. Corker said he was alarmed about a president who acts “like he’s doing ‘The Apprentice’ or something.”

“He concerns me,” Mr. Corker added. “He would have to concern anyone who cares about our nation.”

Mr. Corker’s comments capped a remarkable day of sulfurous insults between the president and the Tennessee senator — a powerful, if lame-duck, lawmaker, whose support will be critical to the president on tax reform and the fate of the Iran nuclear deal. …

… In an interview with The New York Times on Sunday, Mr. Corker responded to a series of Twitter attacks on him by Mr. Trump. He said that the president was running the White House like it was “a reality show” and with bellicose threats that could set the nation “on the path to World War III.” Mr. Corker added that “every single day at the White House, it’s a situation of trying to contain him.”

Other Republican lawmakers, while privately nodding their heads, remained conspicuously silent on Monday morning, and many Senate Republicans no doubt were relieved not to be in session this week in Washington, where they would be intercepted in the hallways of the Capitol by reporters asking them to comment on Mr. Corker’s remarks. …

… Mr. Corker expressed concern shortly after the inauguration that Mr. Trump was a “wrecking ball” to American foreign policy but he largely tempered his criticism in hopes of helping to steer the nation’s first president to serve without any political or military background.

By last week, that hope was clearly gone. As Mr. Tillerson publicly denied he was considering resignation without denying that he had once called the president a “moron” — he let a spokeswoman deny it later — Mr. Corker volunteered that the secretary of state and two other officials were the only thing that “separate our country from chaos.”

Mr. Trump responded over the weekend by calling Mr. Corker “a negative voice” who “didn’t have the guts to run” for another term. Mr. Corker fired back on Twitter by saying “the White House has become an adult care center” and “someone obviously missed their shift.” He followed up with the Times interview. …
