I think Canada played a pivotal role during the three months when the Maidan was fighting a corrupt authoritarian regime in Ukraine.
I would be looking for Canada to take the same leadership role in pushing the agenda forward. In terms of that agenda forward, as I always say, when you're speaking to a thug, you need to speak a thug's language. The only way the situation in Ukraine changed was when sanctions were threatened. Then the country started to make the necessary steps in order to implement them. I think the same thing needs to be done in this critical situation.
When somebody blatantly violates international obligations, it is not sufficient to deplore and to condemn. Concrete actions must be imposed immediately in order to make not only the president of Russia but also his entourage feel that there are serious consequences to this type of violation. That is the only thing that will make them change their minds or de-escalate the conflict.
Canada can play a lead role in pushing that agenda forward.
