Question

during the vietnam war, antiwar protestors believed that nixon’s policy of vietnamization
was an appropriate response to their demands.
would not be implemented during the 1960s.
would actually escalate the war in indochina.
did not end us involvement in the war quickly enough.

Explanation:

Vietnamization was Nixon's policy to transfer combat duties to South Vietnamese forces while gradually withdrawing U.S. troops. Antiwar protestors wanted an immediate end to U.S. involvement, so they viewed the slow pace of withdrawal as insufficiently quick. The other options are incorrect: protestors rejected the policy, it was implemented in the late 1960s, and it was meant to de-escalate U.S. involvement, not escalate the war.

Answer:

did not end US involvement in the war quickly enough.
