betting is goyslop. go bet it on polymarket if you want. I think there is a chance Iran just cucks out and surrenders, which would forestall a draft (they'll still do it for something but it might take longer).
what I dispute is your belief in the fiction about congress, votes, and public opinion. the factors that determine a draft are strategic and material, the political decision is made in tel aviv, the city of london, and rome, with no consideration for democracy.
