"it doesn't provide a viable alternate strategy for negotiations ." That wasn't the purpose of the memo nor is it the purpose of anyone but the government to decide how they are going to negotiate. There has been lots of talk about the standard boiler plate that they the Liberals were open to advice about how to negotiate. In fact much was made of the former PM Brian Mulroney opening doors for them. Except no government wants to be seen as not knowing how to negotiate,and how much of that so-called advice is taken is debatable. They might listen but their minds were already made up as to how they were going to negotiate. The inclusion of aboriginal rights, gender rights and climate change in the talks didn't come from outside sources. Now if the talks were to fail I am sure there will no shortage of people to blame, and they won't be Liberals.
