Note to Canada: it is not "terrorism" to kill soldiers of a country at war.

One can argue it is treason for a Canadian to thus take sides against his own country.

The ethics of this are a complicated question. Was Mr Rouleau fighting on behalf of Iraqis devastated by Bush's conquest and occupation of Iraq (done with Canada's help), or was he fighting on behalf of the PISSI which is more cruel than Bush ever dreamed of being?
