Who told you I support or justify Canada's military operations anywhere? I have no influence over it... (unlike U.S. but that is another topic). In fact, I do not support any countries military operations outside their own territory (I support the military as a defensive force), much less to "protect business interests abroad"
In your case you are justifying U.S. military operations to protect "business interests outside the U.S", and my question was pretty simple.
