The death of Margaret Thatcher marks the passing of a generation of leaders who literally remade their world. The former British prime minister was universally known as the “Iron Lady” for her steadfast commitment to anti-communist and free-market principles. Her passing is a loss to her people, to Americans – who knew in her time the full meaning of a “special relationship” between her country and ours, and to the Free World in which she was a truly heroic figure.
