Policy Paper Concerns

My concerns about my paper are that it is not long enough and that my solution may be too simple. I am unsure if my justification is strong enough or if I should continue saying why other solutions would not work. There are many problems surrounding Japan's whaling policy and I tried to narrow it down to their unnecessary scientific research, bribing developing countries, and the possibility of the moratorium being lifted. I just want to make sure the complex problem is clear enough in my paper.
