With little explanation and no real denials, President Trump has flip-flopped on a dizzying array of policies in a stunningly brief period of time.

China as a currency manipulator. The future of the Export-Import Bank. NATO’s relevance. A federal hiring freeze. The Federal Reserve chair. The wisdom of low interest rates. Syria air strikes. Russia as friend or foe.

Taken individually, the reversals of just the past week seem to prove the oft-stated point that Trump is not bound by even his own past words – that even Trump does not take his words literally.

It’s no coincidence that Trump has shunned his “America first” populism at the same time that he’s sidelined chief strategist Steve Bannon, and as several products of the Goldman Sachs international corporate structure have seen their stars rise.
