briefly explain, what happened that pulled America into the war, what Wilson says the goals of our fighting would be, and why Wilson believes the fight is so important. (Wilson's speech to congress)

On April 2, 1917 President Woodrow Wilson addressed a joint session of Congress to request a declaration of war against Germany. When the Germans resumed sinking our ships without warning, the United States declared war on Germany and fought on the side of the Allies.  

It was a somewhat surprising turn of events. Earlier in his presidency, Wilson coined the phrase “America First,” and his supporters proudly waved banners at the 1916 Democratic National Convention extolling, “He Kept Us Out of War.” Now Wilson was explaining that “Neutrality is no longer feasible or desirable where the peace of the world is involved.”

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
