The role of foreign minister is one based on relationships and experience. When they change constantly, it makes things more challenging. During the campaign for the UN Security Council, we essentially had three different ministers. When you have one who starts to have relationships with counterparts, then all of a sudden you have to change.... Obviously, the world of politics has its complexities and some things can't be helped.
I will go on the record to say that having some tenure in the role of foreign minister is key to success for a country like Canada.
