Problem
This major war, which killed as many Americans as Vietnam, gets onlv a two-page treatment here. Remember the concessions given to Stalin at Yalta in return for his agreement to help with the final defeat of Japan. As a result of this. Russia occubied the northern halt of the Korean veninsula and the United States the southern halt. Two separate antagonistic countries evolved. In June of 1950. the North Koreans crossed the th parallel in an attempt to deteat the south and unity the country. why do the authors say on p. 883 that this invasion provided proof to fruman of the fündamental premise of the "containment doctrine".
