If we won the war, why are we negotiating?
It wasn't a war, and Y OU didn't win anything,
Brad.
Certainly not an understanding of history.
Some examples for you . . .
American Revolutionary War: The United States won and negotiated directly with Britain. The Treaty of Paris (1783) formally ended the war; Britain recognized U.S. independence, set generous western boundaries (to the Mississippi River), and agreed to evacuate all forces while restoring pre-war property rights and fishing privileges.
War of 1812: The Treaty of Ghent (signed December 1814, effective February 1815) restored pre-war borders with no territorial changes, ended hostilities, and included provisions for future boundary commissions and cooperation against the slave trade.
Mexican–American War: Treaty of Guadalupe Hidalgo (1848) — Mexico ceded ~55% of its territory (including present-day California, Nevada, Utah, New Mexico, most of Arizona, and parts of Colorado, Wyoming, Kansas, and Oklahoma) to the U.S.; recognized the Rio Grande as the Texas border; U.S. paid Mexico $15 million and assumed certain debts.
Spanish–American War: Treaty of Paris (1898) — Spain relinquished sovereignty over Cuba (which gained nominal independence under U.S. influence); ceded Puerto Rico, Guam, and the Philippines to the U.S. (U.S. paid $20 million for the Philippines).
World War I: Treaty of Versailles (1919, primary treaty with Germany) — Germany lost Alsace-Lorraine to France, territories to Poland (including a “Polish Corridor”), and all overseas colonies; military severely restricted (army limited to 100,000, no air force/tanks/submarines); Rhineland demilitarized; war-guilt clause imposed; massive reparations agreed to.
World War II: The United States (as part of the Allies) negotiated and signed the Armistice of Cassibile on 3 September 1943 with the Italian government under Pietro Badoglio. This ended hostilities between Italy and the Allies and allowed Italy to switch sides.
