Nuts. Leading by example is a lot easier than any other way of leading unless one has the amount of force available. I doubt even the US has to force available to tell the rest of the planet to smarten up green wise. If you come over here and tell me my kitchen has a dirty floor when yours has dirty dishes in it, you'll get the Turdeau salute.
Everone is so interested in telling everone else how to live their lives, they ignore what's wrong with themselves. It's friggin stupid.
Um, larger countries than Canada? There is only 1, BTW.
