You know, I am not sure where the party is at regarding involvement in the UN. I think you may find a diverse response to your question. I am very certain that most members would be concerned with some of the actions of the UN. By reading the platform you could get a feel for what those things may be.
Personally I know that we are vested in the UN and I do not expect that to change. I understand that the ASP will never be a major player in federal politics. I believe that we could influence on several levels. So, for me, I think I am most concerned with the Democrats and Republicans when it comes to the UN. I always thought I would like to see a bit more isolation from the US, but I do not like how we are currently getting there.
