Context_10 : During the Iraq War, which began with the 2003 invasion of Iraq, there were United States military personnel who refused to participate, or continue to participate, in that specific war. Their refusal meant that they faced the possibility of punishment in the United States according to Article 85 of the US Uniform Code of Military Justice. For that reason some of them chose to go to Canada as a place of refuge. The choice of these US Iraq war resisters to go to Canada has led to considerable debate in Canada's society, press, legal arenas, and political arenas. Much of the debate on this issue has been due to the controversial nature of the Iraq War itself. Among the many elements of that debate are Canada's relationship to the Iraq war, and Canada's relationship to the US, its largest trading partner. fact_1 :  Known as the widow of US Navy SEAL Chris Kyle, she was portrayed by Sienna Miller in the 2014 film "American Sniper" about her husband's life. fact_2 :  Kyle served four tours in the Iraq War and was awarded several commendations for acts of heroism and meritorious service in combat.
