Resolution
The war seemed like it would not end anytime Dwight D. Eisenhower strongly criticized President Harry S. Truman for his handling of the war. When he ended up winning the election, he fulfilled his promise "to go to Korea". His trip had convinced him that he needed to break the diplomatic logjam at the peace talks that had begun in July 1951. He began to publicly hint that the United States might need to make use of nuclear weapons to break the military stalemate in Korea. He also pressured South Korea to drop some of its demands to speed up the peace process.
"Whether or not Eisenhower's threats of nuclear attacks helped, by July 1953 all sides involved in the conflict were ready to sign an agreement ending the bloodshed. The armistice, signed on July 27, established a committee of representatives from neutral countries to decide the fate of the thousands of prisoners of war on both sides. It was eventually decided that the POWs could choose their own fate--stay where they were or return to their homelands. A new border between North and South Korea was drawn, which gave South Korea some additional territory and demilitarized the zone between the two nations. The war cost the lives of millions of Koreans and Chinese, as well as over 50,000 Americans. It had been a frustrating war for Americans, who were used to forcing the unconditional surrender of their enemies. Many also could not understand why the United States had not expanded the war into China or used its nuclear arsenal. As government officials were well aware, however, such actions would likely have prompted World War III."

Implications:
The resolution did help the South and North come to an agreement. Even if they still don't have good relations to this day, at least there is no more war even if citizens of North Korea are fighting their own way in their own country to this day. It did help stop the spread of communism to South Korea and the US did its best to help. The use of nuclear weapons would only cause more deaths and we stopped this war to save millions of lives.
