I think this could be USAID trying to get a bigger part of the budget pie. In my view, humanitarian aid has a marketing problem, and countries respond really well to the idea of being security partners compared to the pittance offered them in foreign aid for a variety of reasons. Additionally, people get tired of sending aid to X country that doesn't seem to get any better or do us a favor because we send them millions in aid (actual development outcomes not being discussed because that's a whole nother can of worms). But, if you frame that to say, hey, we can help with security, or we can structure this aid so that X country in Africa sells us rare Earth elements to make our fancy gadgets 20 years down the road rather than the Chinese, ears perk up a little higher. Same end goal of development, but far more buy-in for simply different reasons.
