Trump promises. What happened?

A quote from Trump.

Trump says that the US needs to focus on itself – and not on “nation building” abroad.

“The United States owes $19tn,” he said. “We have to straighten out our own house. We cannot go around to every country that we’re not exactly happy with and say we’re going to recreate [them].

“It hasn’t worked” he continued. “Iraq was going to be a democracy. It’s not gonna work, OK? It’s not gonna work and none of these things will work.”

What happened!?!'!
