Unfortunately, the answer for your question lies beyond our cut-off point of discussion (1994). This has to do more with modern day attitudes to the armed forces of the United States rather than anything historical.

However, let me reassure you that the negative view towards American soldiers in Vietnam have been grossly exaggerated through popular culture. Few soldiers ever experienced being looked down upon by protesters and the Anti-Vietnam movement themselves didn't see them as baby killers: they saw them as victims of a 'criminal regime'.
