Well, if you want to take all the guilt upon yourself no one will stop you.

But I fail to see why Canada, which is hardly the world's largest arms exporter. In 2006, the "Big 15" exporters were, in order

US
UK
France
People's Republic of China
Japan
Germany
Russia
Italy
Saudi Arabia
India
South Korea
Canada
Australia
Brazil
Spain

(look up the source yourself; I'm not going to do all your work!)

Hell, when you rank well behind France, Japan, and Italy....
