'A new phase': Trump shifts on core issues at a dizzying pace at a critical moment in his presidency

Alex Conant took a long pause to consider the question.

Which seemingly unthinkable shift undertaken in recent days by President Donald Trump stood out to him as the most surprising?

"There's been so many," Conant, communications director for Sen. Marco Rubio's 2016 presidential campaign, told Business Insider.

After some thought, he settled on Trump's change in posture toward Russia.

"He was very consistent on the campaign trail about wanting to have a good relationship with Vladimir Putin. He knew that bombing Assad was going to hurt that relationship, and yet he went ahead with it," Conant said of Trump's decision to launch Tomahawk missiles at Syrian government targets last week.

"What seemed like a big priority for him on the campaign trail became less of a priority once he was in office," he added.

That statement could be made about a laundry list of issues on which Trump has altered his stance — many of which just within the past 10 days.

The shifts have come at a dizzying pace.

Trump bombed an airfield in Syria as retribution for a brutal chemical weapons attack launched by Assad on Syrian civilians, a split from his promises to only go after ISIS. As a result, as Conant said, Trump angered Putin, who has tied himself closely to the Assad regime.

Also in the last week, Trump made a hard turn on China, saying the country was not manipulating its currency less than two weeks after calling them the "world champions" of the practice. A hallmark of his campaign, Trump had promised to label China a currency manipulator on the first day of his presidency, but a meeting with Chinese President Xi Jinping helped to change his mind, as Trump saw an option to negotiate with the Chinese leader over North Korea.

NATO, the transatlantic alliance that Trump famously said was "obsolete" was suddenly "no longer obsolete" on Wednesday, after a meeting with Secretary General Jens Stoltenberg. The US Export-Import Bank, which Trump railed against in the campaign as "unnecessary," became "a very good thing." And Federal Reserve Chair Janet Yellen, whom he criticized in the campaign, was now, in Trump's opinion, doing a good job.

The moves have coincided with a shakeout in the power structure at the White House. Elevated is the centrist, Wall Street wing, headed by National Economic Council Chair Gary Cohn, son-in-law and senior adviser Jared Kushner, and Ivanka Trump, the president's daughter who recently took on a White House job as an assistant to her father. Losing out in this battle have been conservative nationalists, such as chief strategist Steve Bannon.
