Conventionalizing Deterrence? U.S. Prompt Strike Programs and Their Limits
About a decade ago, the U.S. started to examine options to develop and acquire Conventional Prompt Global Strike capabilities. This move fits in an effort to conventionalize deterrence, an effort initiated decades before and undertaken for profound and diverse motives. Although it has been renewed under the Obama administration, which aims to reduce the U.S. reliance on nuclear weapons, this ambition has resulted in very little concrete progress.
Support independent French research
Ifri, a foundation recognized as being of public utility, relies largely on private donors – companies and individuals – to guarantee its sustainability and intellectual independence. Through their funding, donors help maintain the Institute's position among the world's leading think tanks. By benefiting from an internationally recognized network and expertise, donors refine their understanding of geopolitical risk and its consequences on global politics and the economy. In 2024, Ifri will support more than 70 French and foreign companies and organizations.
