The correct answer to this open question is the following.
President Donald Trump changed the course of several US foreign policies.
These are the matches.
Negotiations with Korean Peninsula - nuclear disarmament discussions.
Joint Comprehensive Plan of Action - pulled out of an agreement.
United States-Mexico-Canada Agreement - renegotiated NAFTA.
In this last case, President Trump asked the other two presidents to renegotiate the terms of the trade agreement.
Originally, the North American Free Trade Agreement (NAFTA) wanted to generate many positive factors for the three countries, Mexico, Canada, and the United States. But as always happen in free trade agreements, the reality shows many different ourcomes for the three of them.
That is why the Congresses of the three countries analyzed the new free trade agreement.
The new agreement is called “USMCA” or United States-Mexico-Canada Agreement and was signed on September 30, 2018.
