Problem: In April 1950, Stalin gave Kim permission to invade the South under the condition that Mao would agree to send reinforcements if they became needed. Stalin made it clear that Soviet forces would not openly engage in combat, to avoid a direct war with the Americans. Kim met with Mao in May 1950. Mao was concerned that the Americans would intervene but agreed to support the North Korean invasion. China desperately needed the economic and military aid promised by the Soviets. At that time, the Chinese were in the process of demobilizing half of the PLA's 5.6 million soldiers. However, Mao sent more ethnic Korean PLA veterans to Korea and promised to move an army closer to the Korean border. Once Mao's commitment was secured, preparations for war accelerated.

Problem: By 1640, the town's theocratic government and nine-square grid plan were in place, and the town was renamed Newhaven from Quinnipiac. However, the area north of New Haven remained Quinnipiac until 1678, when it was renamed Hamden. The settlement became the headquarters of the New Haven Colony. At the time, the New Haven Colony was separate from the Connecticut Colony, which had been established to the north centering on Hartford.
