Obama has spent the last eight years on an American apology tour. Many of these agreements, such as NAFTA, are outdated. It's time for Trump to renegotiate them so that American businesses can come first in America. He is showing that he wants to be a strong leader for the good of the country.
America has benefited greatly from the North American Free Trade Agreement. NAFTA has also brought increased economic opportunities to Canada and Mexico as well. Renegotiating NAFTA might destabilize the North American economy, creating uncertainty about the future relationship of the United States with Mexico and Canada. Instead of trade wars, America should focus on tax and regulatory reform to promote manufacturing at home.
NAFTA has been a contentious agreement for years, with some saying it works while others just hate it. It may not hurt to take a good long look at the agreement to see if it is still accomplishing what it was meant for. If it isn't, then maybe some renegotiating should take place.
Though NAFTA has problems, for Trump to sign an executive order to plan to renegotiate it should be thought of as a publicity stunt to satisfy his base. Neither Trump nor the heads of his cabinet are knowledgeable enough about NAFTA to begin to know how to renegotiate it. Congress will consider renegotiating NAFTA a low priority, and it will only cause dismay among the governments and people of Canada and Mexico.
