We have to remember when we talk about the United Nations, there is no such thing as the United Nations. It's of course a whole bunch of different nations, all of whom have slightly different positions and policies and goals on any issue, including Sri Lanka.
Some may be thinking very constructively, okay, if we're going to move forward with some sort of UN led investigation there, it's really only going to be effective if we get Sri Lanka on side. So let's constructively think of the way to do so. There are other nations who aren't thinking constructively but obstructively. They're receptive to Sri Lanka's pleas to block this, and Sri Lanka is saying, we don't want this to happen, so stand with us in opposing this.
The strategies need to take account of both of those possibilities. Ultimately we may reach a point where it becomes clear that it's going to be absolutely impossible to obtain any kind of cooperation and collaboration from the Sri Lankan government, and at that time we and other organizations might say to UN member states, you have to move forward with it anyway. Here's the way you need to do so, even without Sri Lanka's collaboration and cooperation.
