In 1969, the most important issue in American foreign policy was still the Vietnam War. In that sense, the US's foreign policy continued to be one of containment since that war was more about containment than about anything else.
The US was soon to embark on the policy of detente, but that policy really started with Nixon's engagement with China. He had yet to start with that policy in 1969.
Within the context of the Vietnam War itself, the foreign policy of the US was Vietnamization. The US was trying to hand the war over to the Vietnamese. However, this was more of a tactic than a strategy. The main focus of US foreign policy at that time was still the containment of communism.
