- Donald Trump, from a 2016 Republican Presidential Primary debate, he would later specificically cite Iraq, Libya, Egypt and Syria as examples.
"We need to stop racing to topple foreign regimes, that we know nothing about, that we shouldn't be involved with."
- Donald Trump, in a 2015 interview with Sean Hannity, where he called Barack Obama and Hillary Clinton "war-mongers."
This is a remarkable shift in ideology.
