So, in early 2018, USAID will launch a new Humanitarian Assistance Grand Challenge.  It will be our 10th Grand Challenge.  At the core of each Grand Challenge is our belief that when government works with the private sector and with innovative and entrepreneurial leaders, there's no limit to what it is that we can do.  We can come up with better ideas, better solutions, better methods.  And I hope our Humanitarian Assistance Grand Challenge will help us better tackle some of the daunting challenges that we see right in front of us.
