DONALD TRUMP’S FOREIGN POLICY

China reacted harshly to President-elect Donald Trump’s attacks on its economic and security positions yesterday, China’s foreign ministry spokesperson indicating that Beijing had made its unhappiness directly known to members of Trump’s team, Damian Paletta, Carol E. Lee and Jeremy Page report at the Wall Street Journal.

China called on the US not to allow Taiwan’s President Tsai Ing-wen to transit there when she visits Guatemala next month, Ben Blanchard and Bill Barreto report at Reuters.

President Tsai Ing-wen’s phone call with Donald Trump should not be interpreted as a significant shift in US policy, she said today, stressing that both nations see the value of maintaining regional stability. Lavanya Ramanathan and Simon Denyer report at the Washington Post.

The prospect of a change in US policy should be prompting closer attention, argues Tom Ackerman at Al Jazeera.

Trump’s unprecedented phone call to Taiwan’s president and subsequent tweets criticizing China raise the possibility of major friction between the world’s two largest economies, Christopher Bodeen an AP setting out six areas that could develop into flashpoints.

People in Taiwan are bracing for Chinese retaliation following President Tsai Ing-wen’s phone call with Trump, fearing that Taiwan and not the US will be the focus of Beijing’s anger, Andrew Browne writes at the Wall Street Journal.

The Iraq war was probably a “mistake,” according to Trump’s nomination for secretary of defense Gen. James Mattis – but if he was among those who disagreed with President George W. Bush at the time, he did a good job of hiding it, writes Mattathias Schwartz at The Intercept.

Rep. Ruben Gallego (D-Ariz.) became the second lawmaker to state that he would not back a waiver for Mattis to serve in the position of secretary of Defense within seven years of his retiring from military service, the Hill’s Rebecca Kheel reports.

The problem with Trump’s appointment of a team of generals to his national security and foreign policy Cabinet is that it emanates from and exacerbates the public’s enormous deference to the military on issues of war strategy and its support for a broader role for the military than the traditional civil-military balance allows for, writes Daniel W. Drezner at the Washington Post.

State Department officials are increasingly concerned that Donald Trump’s children will assume the role of freelance ambassadors, further blurring the line between their own business affairs and America’s foreign affairs, and the warning signs are already there, writes Nahal Toosi at POLITICO.

For Trump, a successful foreign policy in the Middle East will rest on a successful Iran policy, and there are some important lessons he can learn from his predecessors, suggests Ray Takeyh at POLITICO.

The Ukrainian government has more reason than most to fear the Trump administration, Shaun Walker writes at the Guardian, recalling that the President-elect has made a number of positive comments about Russian President Putin and even suggested he might consider recognizing Crimea as part of Russia.

While Trump may not be another Hitler, America could become another Wiemar Germany, suggests Richard Cohen writing at the Washington Post.

Ongwen pleaded not guilty to 70 charges including murder, rape, forced marriages and using child soldiers this morning, Mike Corder reports at the AP.
