The policy challenge is strikingly similar to the one of ending poverty and hunger in the world. America is remarkably generous (The US, Canada and Australia last year took in 92% of the world's resetlled refugees), but the scope of the problem is tremendous: the US, for example, will resettle about 75,000 people, but 13.6 million others worldwide are living under or seeking UN protection. The American system is creaking: new arrivals received assistance for 24 months when the current system was installed thirty years ago in the Carter Administration, but that's down to a maximum of eight months today.
Wiltenburg's political analysis applies to hunger and poverty, too:
"Refugee resettlement is a tiny program in the grand scheme of Washington. It has no real opponents, but advocates all have higher priorities and the refugees themselves have no political clout. It’s widely agreed that the program’s funding is due for a radical increase [but] how any politician will weigh the moral and political costs against the financial one is still a question."
National security rationales are often used to lobby for international relief programs of all kinds, but the logic is usually tenuous. The true motivation is compassion and generosity, which is unfortunately antithetical to the competitive tussle over resources that is the essence of politics.
