What is one way in which americans believe that the united states could have won in vietnam? by fighting more battles at sea with the vietcong by encouraging the north vietnamese to fight harder by challenging the vietminh to a re-match at dien bien phu by using its military power quickly and without limit?

The correct answer is by using its military power quickly and without limit?
