Yes, that's a good point. But you have to keep in mind that these are appeals about needs that they anticipate. They don't currently have 700,000 refugees to respond to; they're anticipating that by the end of 2012 they will have that many. Right now they have 40% of the required needs, and based on access and trends, they anticipate 700,000 by the end of 2012.
Donors are keeping up in responding systemically. Yes, there are needs that perhaps could be met additionally, but the needs do continue to be met.
I was in Geneva two weeks ago to meet with UNHCR, and they said they are doing quite well with the response for the Syrian refugees.
