Danilovich was fresh from a meeting with America's traditional Nicaraguan nemesis, President Daniel Ortega. Venezuelan dictator Hugo Chávez has been courting Ortega and his leftist Sandinista comrades with elaborate (and so far unfulfilled) promises of aid. But Danilovich found Ortega enthusiastic about Nicaragua's MCC compact, which helps increase the income of rural farmers. The MCC is the main counterweight to Chávez's influence in that country, allowing America to maintain ties with the Nicaraguan people even as political relations with the government grow complicated.

This program also provides tangible rewards for reform in the Islamic world. A compact with Morocco is due to be announced late this month. Jordan is working toward its own agreement. And when Yemen was suspended from the MCC in 2005, it undertook a series of anti-corruption reforms in order to be reinstated.

Danilovich calls this "the MCC effect." Since the global competition for compacts is vigorous, nations are willing to make major changes to receive them.

In Lesotho, parliament has granted married women the right to own land -- previously they were considered legal minors -- in order to qualify for MCC aid. In Georgia, the government fired 15,000 corrupt policemen. When I worked at the White House, the finance minister of an African country seeking MCC funds once said to me: "I keep telling others in my government that we've got to do better fighting corruption. We've got to compete."

The same Pew survey that shows growing anti-Americanism reveals something more hopeful: Eight of the 10 countries most favorable to the United States in the world are in sub-Saharan Africa. It is not a coincidence that American bilateral assistance to African countries over the past six years -- to fight AIDS, malaria and poverty -- has quadrupled. As a rule, people do not hate you when you save their children.

Congressional reductions in MCC funding would bite agreements on the African continent first. Tanzania could have its compact reduced significantly. Burkina Faso might be cut off entirely. Then Jordan and Bolivia could have their agreements delayed indefinitely. And our country would forgo a great deal of goodwill.

America needs tools of influence other than the tools of war. And when we have them, they should not be carelessly discarded.
