Tensions with Mexico, then in the throes of a violent civil war, escalated almost to the point of warfare. The U.S. sent military forces to chase Pancho Villa and to control the port of Vera Cruz. In 1917 both parties pulled back, and by 1920 the civil war was over.

More serious was the worldwide Great War (now called [[World War I]] that began in 1914 and was killing millions of soldiers to no apparent end. Proclaiming neutrality, President [[Woodrow Wilson]] tried repeatedly to broker peace in 1915-1916, but the adversaries in Europe were both planning to win and did not want a negotiated settlement. After Germany started sinking American merchant ships in 1917, and tried to entice Mexico into going to war with the U.S. Wilson in April 1917 asked and received a declaration of war from Congress. Wilson argued persuasively that it was now necessary to fight against militarism and for democracy in the world. He set up a draft and trained millions of soldiers, sending the [[American Expeditionary Forces]] to the [[Western Front]] in France under the command of General [[John J. Pershing]]. The Americans and the Allies defeated the Germans in late 1918—the so-called "armistice" was in effect a German surrender.

Wilson, aided by his top advisor [[Colonel House]], played a dominant role in ending the war with his [[Fourteen Points]] and played the central role at the 1919 [[Paris Peace Conference]] that set the peace terms. Wilson failed to obtain Senate approval for the [[Treaty of Versailles]] because it required American entry into the [[League of Nations]], and Republicans led by Senator [[Henry Cabot Lodge]] demanded amendments (called "reservations") to protect American sovereignty, which Wilson rejected. The League went into operation but was ineffective; the U.S. never joined it.

===Korean War: 1950-1953===

The [[Korean War]] began at the end of June 1950 when North Korea, a Communist country, invaded South Korea, which was not under explicit American protection. Without consulting Congress Truman ordered General [[Douglas MacArthur]] to use all American forces to resist the invasion. Truman then received approval from the United Nations, which the Soviets were boycotting. UN forces managed to cling to a toehold in Korea, as the North Koreans outran their supply system. A counterattack at Inchon destroyed the invasion army, and the UN forces captured most of North Korea on their way to the Yalu River, Korea's northern border with China. Truman defined the war goal as [[rollback]] of Communism and reunification of the country under UN auspices.

In late 1950 China intervened unexpectedly, drove the UN forces all the way back to South Korea. The fighting stabilized close to the original 38th parallel that had divided North and South. MacArthur wanted to continue the rollback strategy but Truman arrived at a new policy of containment, allowing North Korea to persist. Truman's dismissal of MacArthur in April 1951 sparked a vehement debate on American Far Eastern policy, as Truman was blamed for a high-cost stalemate with 37,000 Americans killed and over 100,000 wounded.
