For you to say MW was unenthusiastic about the war is extremely harsh, just the same. We lost over half of our total alliance strength, we kept our members out of peace and fighting the whole time we were in the war and we took on 4 different alliances who came at us officially and 3 more who came at us without a formal DoW. We threw everything into the war that we had. For a 46 member alliance, (56 if you want to count our 10 trainees) we gave everything we could. We didn't have to get involved in the war. We had no treaty forcing us to take part. We went in to help our allies, plain and simple.
If we were unenthusiastic about the war, we never would have gotten involved in the first place and we would have taken the first offer at peace that was sent to us, which we did not.
