Jus ad bellum and Canada's war in Afghanistan

The purpose of this study is to examine the utility of a just war explanation in understanding Canada’s decision to enter into the war in Afghanistan. It examines Canada’s three phases of the war under the lens of jus ad bellum. The concentration is upon jus ad bellum’s core criteria of legitimate authority, public declaration of intent, just cause, last resort, reasonable chance of success and proportionality and then applies it to the three phases. By examining Canada’s international role, paying close attention to Canada’s association with the UN, NATO and its ally status with the United State are important explanations of why Canada entered into the Afghanistan war. This analysis strives to provide a holistic comprehension by exploring the utility of an ignored body of explanation and extrapolates from this analysis the contemporary use of jus ad bellum.
