When one looks at the scale of Syria's need, it is clear that the international community cannot do enough and indeed has not done enough. The heart of the matter - support and pressure for a political settlement - is flatly blocked within the UN Security Council. Humanitarian aid appeals meet with a response, but never quite to the amount sought. For the UK, we responded - £200million to the latest appeal - and will continue to respond. And we do all we can to unblock the path to that political settlement that Syria needs.
