I think the shorter answer here is to defer to the OSCE. I think the OSCE is doing what it can, but if we want to decrease the violations of the ceasefire, then we're going to need to have the OSCE out at night. Basically it's calm during the day and then at night everybody shoots at each other, because at night it's very difficult to ascertain who started it.
Thinking of a peacekeeping mission is thinking several steps too far. Let's just work with the monitoring regime we have in place and what we can do to shore up the OSCE and that monitoring regime. The OSCE is important because we have Russia as part of the effort going forward.
I've argued that this is also in Canada's strategic interest in places like Syria. Eventually people are going to stop shooting. If all the major powers are involved, somebody with leadership at headquarters is going to have to step up. This has been true of some of the contributions we've made in the Golan Heights and in Israel for over the past four decades. Canada will want to tread carefully, though, because everybody is so involved in the Ukrainian conflict that we don't know who is going to step up if that call comes. Anything that reduces the conflict and the tension is clearly in Canada's strategic interest.
