Feed them on the ground and bomb them from the sky. That's, seemingly, the US policy towards Yemen. In the following clip, the USAID in cooperation with other institutions depict their work on the ground as rosy as possible. They showed how charitable they are in Yemen. It might seem irrelevant question to ask but "why didn't they mention the CIA's drone strikes committed targeting hundreds of civilians in Yemen in the name of "the war on terrorsim"!!!"
For what's worth, I must say, I have nothing against the "civil society" NGOs in US working in Yemen. My objection is on the US administrations' policies!!
