Disruptor in Chief: How Trump is changing world order

(CNN)The US emerged from World War II as a superpower aiming to shape the globe in its own image. America's alliance with European powers sought to prevent another catastrophic conflict by founding institutions dedicated to defending democracy, human rights and free markets across the world.

Even before assuming the presidency, Donald Trump was shaking confidence in these grand designs.
"It's a global power structure that is responsible for the economic decisions that have robbed our working class, stripped our country of its wealth, and put that money into the pockets of a handful of large corporations and political entities," presidential candidate Trump crowed to his supporters a month before they voted him into office.
    Since his election, Trump has followed through on his promise to distance the US from global pacts it helped forge. He's withdrawn from the Paris Agreement on climate change, ignored NAFTA and the World Trade Organization by launching trade wars on allies and even called into question the role of NATO.
      US allies decry Trump as hammering at the braces of the Western alliance and emboldening Russia and China to lead aggressive military expansions.
      Still, the President's backers call his decisions good 'America first' policy.

      America's loss of the moral high ground and unwillingness to engage has resulted in a contagion of authoritarian overreach around the globe.
      There is a sense that the once self-styled "world's policeman" has neither the will nor the moral authority and we are living with the consequences of that.
