“We must make every effort to avoid the fall of the first dominoes. There is still time ”  WTO Director General Roberto Azevedo  told the heads of WTO delegations at a closed-door meeting in Geneva.
“In light of recent announcements on trade policy measures  it is clear that we now see a much higher and real risk of triggering an escalation of trade barriers across the globe ”  Azevedo  said  according to a copy of  his  statement released by the WTO.
 Azevedo  is normally very conservative in remarks about WTO members’ trade policies  but  he  also plays a role as a guardian of the global trading rules  a bulwark against protectionism.
On Friday  he  broke  his  silence on Trump’s tariff plan  expressing concern and saying a trade war would be in nobody’s interest.
In  his  statement at Monday’s meeting   he  did not name any one country but sounded a more urgent warning.

[Q]: "Storm clouds are gathering" over  the Korean Peninsula  Defense Secretary Jim Mattis  declared Friday. And as diplomats try to resolve the nuclear standoff   he  told soldiers that the U.S. military must do its part by being ready for war.
Without forecasting a conflict   Mattis  emphasized that diplomacy stands the best chance of preventing a war if America's words are backed up by strong and prepared armed forces.
"My fine young soldiers  the only way our diplomats can speak with authority and be believed is if you're ready to go "  Mattis  told several dozen soldiers and airmen at the 82nd Airborne Division's Hall of Heroes  his last stop on a two-day pre-holiday tour of bases to greet troops.
 Mattis'  comments came as the U.N. Security Council unanimously approved tough new sanctions against North Korea  compelling nations to sharply reduce their sales of oil to the reclusive country and send home all North Korean expatriate workers within two years. Such workers are seen as a key source of revenue for North Korean leader Kim Jong Un's cash-strapped government.
At Fort Bragg  Mattis recommended the troops read T.R. Fehrenbach's military classic "This Kind of War: A Study in Unpreparedness " first published in 1963  a decade after the Korean War ended.
Asked about recent reports that families of U.S. service members in South Korea might be evacuated   Mattis  stressed  his  belief that diplomacy could still avert a crisis.  He  said there is no plan now for an evacuation.
"I don't think it's at that point yet "  he  said  adding that an evacuation of American civilians would hurt the South Korean economy.  He  said there is a contingency plan that would get U.S. service members' families out "on very short notice. "
Mattis  said  he  sees little chance of Kim disrupting the Winter Olympics  which begin in South Korea in February.
"I don't think Kim is stupid enough to take on the whole world by killing their athletes "  he  said.
 Mattis  repeatedly stressed that there is still time to work out a peaceful solution. At one point  he  said diplomacy is "going positively." But  he  also seemed determined to steel U.S. troops against what could be a costly war on the Korean Peninsula.
"There is very little reason for optimism "  he  said.

[Q]: (CNN ) FBI Director Chris Wray  upended the White House's timeline about when it learned of domestic abuse allegations leveled against disgraced aide Rob Porter.
 Wray  testified Tuesday that the FBI repeatedly briefed the White House on its investigation into the aide last year  despite how the White House has presented their timeline.
The FBI submitted information to the White House on its background investigation into the former White House staff secretary that uncovered allegations of domestic abuse four times before those allegations became public   Wray  told the Senate Intelligence Committee on Tuesday.  The FBI director 's testimony raises fresh questions about why Porter remained in a senior position after the White House learned of the allegations of domestic abuse leveled by two of Porter's ex-wives to the FBI -- extending a controversy the White House has struggled to shake.
"I can't get into the content of what was briefed to the White House ... What I can tell you is that the FBI submitted a partial report on the investigation in question in March. And then a completed background investigation in late July. That soon thereafter  we received request for follow-up inquiry and we did the follow-up and provided that information in November and that we administratively closed the file in January "  Wray  said in response to questions from Sen. Ron Wyden  a Democrat on the Senate Intelligence Committee.
 Wray  added that the FBI "received some additional information" earlier this month and "passed that along as well."
