Canada can't be really counted as a large country because it's population 1.5 times less than in Ukraine for example and most of them live not further than 100 km from US border. Also about strong leader. What exactly you mean by "strong"? To be strong enough to take responsibility for the decisions you make? Or to be strong enough to treat most of the population like sh!t? In the second sence most of Russian leaders were very strong. But in the first one I'm afraid they are very weak and coward.
