President Theodore Roosevelt's Big Stick Policy was to negotiate peacefully with other countries, but to "carry a big stick", meaning that the countries who you were negotiating with were aware of what could happen if there were some kind of problem. The dollar diplomacy was one used mostly by William Taft to further its aims in foreign countries by offering guaranteed loans if their commercial interests were improved. The Moral Diplomacy was a policy used by Woodrow Wilson, where he would only support countries who had analogous morals with the United States.
The Seven Years' War broke out in Europe while the French and Indian War was being fought in North America.
Hope this helps!
