Let me take a stab at this, Mr. Dewar.
To underline what you said about meagre resources, we have a consensus around which interventions are effective and also have a low cost and a high impact. We have consensus about them. That's what we join together on.
It's not denying anything you've said, but areas where we have international consensus and no Canadian public debate are where we think we should focus. We don't want to lose this opportunity to have a real impact at the G-8 by focusing on something that we don't have consensus on.
