"Well, we think the broadcasts did have some effect, because we see the antiwar movement in the U.S. building up, growing and so we think that our broadcast is a support to this antiwar movement"

Hanoi Hannah's quote suggests that the anti-war movement in the United States was growing and that the broadcasts she was associated with had some result on this growth. This suggests that the broadcasts were supplying assistance to the anti-war movement, which was likely an objective of the broadcasts. This quote also suggests that the anti-war movement was gaining momentum, which could be seen as a positive sign for those who opposed the war. It is most likely that Hanoi Hannah was proud of the function her broadcasts were playing in the anti-war movement and was enthusiastic that the motion would continue to grow and eventually result in an end to the war.
