Republican vice-presidential candidate Sarah Palin is flexing her newly found diplomatic muscles. On Tuesday she met with two heads of states who traveled to New York for the opening of the U.N. General Assembly. She spoke to Afghan President Hamid Karzai and Colombian President Alvaro Uribe one-on-one in a suite of a midtown hotel, according to the New York Times. Meeting with both men could be seen as a major attempt to expand her credentials. McCain's senior foreign policy adviser and a former staff member of the National Security Council were among the guests accompanying her on her visit.
