Measuring impact: $1.7 billion shifted

What is the core public interest case for foreign aid beyond soft power? How should we define safety and prosperity? Why do many voters believe aid is a quarter of the budget when it is a tiny fraction and how does that shape support? How did a political decision to halt awards ripple through real programs and what safeguards failed? What legal and institutional checks should prevent a single administration from impounding funds that Congress appropriated? When government pauses, how can private funders triage the most life saving pieces without letting systems collapse? If an agency is rebuilt, which programs should be protected first and which processes should be redesigned from day one? How do we embed evidence and cost effectiveness at the start of strategy rather than as an afterthought in evaluation? What would it look like to center partner governments in the process so that learning becomes part of their own delivery? How can we avoid a fixation on what is easy to measure while still demanding clear estimates and accountability? What does it mean to meet donors where they are while steering them toward the highest impact use of funds?
