You mean they should just roll over and take the beating instead of punishing alliances that oA into an MDP or those that choose to go after nations that have clearly surrendered? Nuclear weapons are the only way they can get back at alliances when there is clearly no way of winning conventionally. Futhermore, using the radiation update as an excuse for extracting reps from a damaged alliance is a really lazy excuse. If you truly believed that, then I'll be waiting for you to get reps from NK, Fark and all the other alliances that extensively used nukes this war.
You took damage from the war and wanted to get back at them, just admit it. Chola has at least.
