Last year at CGI, I spoke about the Obama Administration’s new strategy for international development, which has elevated development alongside diplomacy and defense as the core pillars of American foreign policy. And we are working with our partner countries to help them obtain the tools and capacity that they need to solve their own problems and contribute to solving the world’s shared problems. Our goal is to help people lift themselves, their families, and their societies out of poverty and toward a better life. And this is not development for development’s sake. This work, we believe, advances our own security, prosperity, and values.
