There are several aspects to this question. I will start to answer it, but then I will likely turn it over to Mr. Hamilton from the Department of Foreign Affairs, Trade and Development.
We are looking at all possible short-term scenarios in Ukraine right now. Of course we're concerned about the escalation by Putin, but we're also looking at what goals he can really achieve given the problems he has had in the last few days of his campaign. We're looking at short-term scenarios and we have begun to look at long-term scenarios as well.
I will turn it over to Mr. Hamilton to complete my response, because this is not simply a military campaign.
