Answer: Option (C). limited war to force negotiations
Explanation: The North Vietnamese was able to frustrate American design for so long and ultimately force the United States to withdraw. They could not hope to match the Americans military power but they believed accurately that they were more than a match for the Americans and their allies in the realms of political power and organization skills. The assumption that the principal and primary means test of success must be military combat was dismissed. The North Vietnamese realized the possibility of achieving a change of war venue and determine its outcome away from the battlefield.
