On 11 April 1951, Commander-in-Chief Truman relieved the controversial General MacArthur, the Supreme Commander in Korea. There were several reasons for the dismissal. MacArthur had crossed the 38th parallel in the mistaken belief that the Chinese would not enter the war, leading to major allied losses. He believed that whether or not to use nuclear weapons should be his own decision, not the President's. MacArthur threatened to destroy China unless it surrendered. While MacArthur felt total victory was the only honorable outcome, Truman was more pessimistic about his chances once involved in a land war in Asia, and felt a truce and orderly withdrawal from Korea could be a valid solution. MacArthur was the subject of congressional hearings in May and June 1951, which determined that he had defied the orders of the President and thus had violated the U.S. Constitution. A popular criticism of MacArthur was that he never spent a night in Korea, and directed the war from the safety of Tokyo.
What did Truman want to see happen in Korea?
****
The answer: a truce and orderly withdrawal

In the late 1800s, Presbyterian missionaries established a presence in what is now northern New Mexico. This provided an alternative to the Catholicism, which was brought to the area by the Spanish Conquistadors and had remained unchanged. The area experienced a "mini" reformation, in that many converts were made to Presbyterianism, prompting persecution. In some cases, the converts left towns and villages to establish their own neighboring villages. The arrival of the United States to the area prompted the Catholic church to modernize and make efforts at winning the converts back, many of which did return. However, there are still stalwart Presbyterians and Presbyterian churches in the area.
Around when did Presbyterian missionaries arrived in New Mexico?
****
The answer:
1800s
