Nicholas Burns, former American diplomat and current professor at the Harvard Kennedy School, joined Chad to react to the current situation in Syria and his thoughts on how the United States need to handle it.

According to Nicholas Burns, a former U.S. ambassador who served Bill Clinton and in both Bush administrations, Trump’s approach in Syria has more in common with Obama’s than either would likely admit. “I think that the president’s tweet yesterday was specific enough that he has effectively drawn a red line as well. I think that the president needs to respond to this.”

The essence of global politics today, said career diplomat and Harvard professor Nicholas Burns in a speech at Bates College, is that no country can go it alone.

Issues like climate change, public health crises, the threat of chemical and nuclear weapons, and cyber attacks are transnational problems requiring transnational solutions. But while a global mindset is more necessary than ever, the United States’ highest leaders are drawing back from the world.

“We’re led by the first president since the 1920s who doesn’t believe that the United States has a fundamental responsibility to help the world be knit together, to be the first responders, to cope with the big problems and the small problems,” Burns said to a Bates audience on March 29.
