I think if former PM Stephen Harper truly has something authentic and real to contribute or offer to the success of Canada's NAFTA renegotiation efforts, then instead of hiding behind the writing of critical non-constructive memos, I would suggest in the strongest possible terms that he follow the lead of former PM Brian Mulroney and become a member of our country's "team", thereby constructively adding his voice/expertise, so as to ensure the greatest possible success/benefit IS achieved from these NAFTA renegotiations for our country and its people period!!  Otherwise Harper, I say shut your pie-hole and/or piss-off please!!!
