Should a country's military be solely concerned with defence of it's borders?
Being in the Canadian Forces for 20 years, I've seen the good and the bad of what a military should be. Aid to civil powers and relief though the UN, showed me what good a government can do with it's armed force. Although, other not so fun places like Afghanistan and the former Yugoslavia showed that a combined force can cause a myriad of problems including deaths.
Is there room in today's army (of any country) to have conscientious objectors? Just how far can we allow discipline lacks before an army becomes infective?
