Milestone-Proposal talk:The First Breaking of Enigma Code by the Team of Polish Cipher Bureau, 1932-39
The Enigma Milestone proposal by the Poland section is well documented and worthy of consideration. However, the citation states that the work helped to shorten World War II. There is no quantifiable evidence by how much the war was shortened. I recommand changing shorten by a non-quantifiable equivalent word, e.g. "end" the war, rather than shorten it.
Two other Milestones were given for subsequent work on breaking the Emigma code. It is very appropriate to equally recognize the original work.
