Before the start of business, Just Security provides a curated summary of up-to-the-minute developments at home and abroad. Here’s today’s news.

DONALD TRUMP’S FOREIGN POLICY

Exxon Mobil Corp. CEO Rex Tillerson has been added to the list of candidates for the post of Donald Trump’s secretary of state, according to one transition adviser, Carol E. Lee and Peter Nicholas observing at the Wall Street Journal that choosing a secretary of state with no foreign policy background like Mr Tillerson could further unnerve government officials serving in an institution that functions on strict protocols.

A running list of the key positions Trump has filled so far is being maintained by the Washington Post and Partnership for Public Service.

Trump’s controversial phone call Friday to Taiwan’s leader was planned weeks in advance as a provocative stunt to demonstrate that Trump is a radical change from previous presidents, Anne Gearan, Philip Rucker and Simon Denyer report at the Washington Post.

Trump is clear about China’s position on Taiwan and China has maintained contact with his team, the Chinese foreign ministry said today, Ben Blanchard and Roberta Rampton reporting at Reuters.

The President-elect took to Twitter to rail against China’s military and economic policy Sunday, David Smith reports at the Guardian.

Trump’s conversation with Taiwan’s leader demonstrated why his presidency has the potential to restore “badly-needed credibility to a host of global challenges,” Rupert Hammond-Chambers argues at the Wall Street Journal.

Trump may have taken the first steps to stabilize East Asia, according to Gordon G. Chang writing at The Daily Beast.

The Pentagon will review its strategy for defeating the Islamic State for President-elect Trump, Joint Chiefs Chairman Gen. Joe Dunford said. Connor O’Brien reports at POLITICO.

Iran and China’s foreign ministers urged governments not to violate the Iran nuclear deal today in remarks the AP suggests were directed at Donald Trump’s incoming administration.

Russian President Putin’s concerns that Trump could be an unpredicable partner were signalled by his recent comments about the difference in level of responsibility for Trump as a businessman and as the President of the US, writes Andrew Roth at the Washington Post.

The election of Donald Trump as president raises the possibility of a dramatic shift in the US’s approach to Syria next January, while major losses by rebels fighting in Syria have scrambled US policy calculations at this crucial moment in Syria’s war, Jay Solomon, Carol E. Lee and Felicia Schwartz write at the Wall Street Journal.

Trump’s contradictory messages to nuclear-armed arch rivals Pakistan and India tell us something about how the President-elect operates: he tells whoever is listening exactly what they want to hear, observes Dana Milbank at the Washington Post.

Trump’s economic nationalism will redefine America’s global role in “a fundamentally deceptive and destructive way,” US leaders having embraced the idea that trade can foster prosperity and promote democratic societies ever since World War II, Robert J. Samuelson writes at the Washington Post.

Homeland security secretary candidate and current House Homeland Security Committee Chairman Michael McCaul (R-Tex.) is going public with detailed and relatively workable plans to turn Trump’s ideasextreme vetting of immigrants and refugees, a border structure with Mexico, and deporting criminal illegal immigrants – into reality, writes Josh Rogin at the Washington Post.

How the Islamic State returned to Syria. Roy Gutman delivers the third and last chapter in his investigation of President Assad’s contributions to the creation of the Islamic State at The Daily Beast.

Assad has been able to maintain the allegiance of a good portion of his citizens by offering them a thin veneer of normalcy, despite waging a relentless counterinsurgency campaign that has led to the deaths of 430,000, displaced half the population and destroyed vast swaths of its cities, Barak Barfi writes at POLITICO.

IRAQ

Iraqi forces have begun shelling parts of west Mosul, residents reported, in preparation for opening a new front against the Islamic State there. [Reuters]

After quick progress at the start, the operation to retake Mosul from the Islamic State is becoming harder, as the realization that the terrorists will not surrender the city sets in, Martin Chulov reports at the Guardian.

While the fight to capture Mosul may be difficult, it is “possible” it could be finished before President-elect Donald Trump takes office, Defense Secretary Ash Carter said today. Idrees Ali reports at Reuters.

Fighters in northern Iraq insist that the sand berms and trenches that are stretching across the region toward Syria, some accompanied by newly-paved roads with streetlamps and checkpoints covered with Kurdish flags, are not the border of a newly independent state – but that could change, Brian Rohan and Balint Szlanko write at the AP.
