1965 the war in Vietnam continues to worsen as whatever the Americans do including the major bombing of North Vietnam they continue to lose more men. Therefore my answer is C.

I believe the answer is: C. began escalating its commitment of troops to the war in Vietnam.

By the year of 1965, the untied states government began to realize that the initial batch of troops that they sent to aid vietnam fight against the communist influence did not the intended progress. Because of this, President Johnson ordered additional 50,000 forces to be deployed to Vietnam to escalate the commitment.
