VASILIEVKA, Kyrgyzstan – The youngsters at Solnyshko preschool in this impoverished village near the border of Kazakhstan were excited to see the American men and women from the nearby air base. They giggled and clapped their hands. Fidgeted in their seats. And waited as patiently as any preschooler is able when the promise of gifts and perhaps even candy is just a few formalities away. “They’re always happy when the Americans come,” the school’s principal, Manzura Kushbaeva, said through an interpreter.
