...Fidel Castro slowly but steadily challenged Batista’s rule in the late 1950s, promising an end to the dismal inequality and extreme poverty in Cuba. Following their victory, the revolutionaries became symbols of an enduring resistance against America and its values less than 100 miles from U.S. soil. Fidel Castro and his regime have since outlasted 10 U.S. presidents, the fall of the Soviet Union, Deng Xiaoping’s market reforms in China, and both the civil rights movement in America and the election of the first African-American president. Despite history, it seems, Cuba marches...

Not only does that raise the risk of accidents like the Kingston spill, but the toxins in the ash could seep into the soil or groundwater, contaminating drinking water supplies. Environmentalists would prefer federal regulations that require ash to be buried in lined landfills that would prevent leakage. "You can't talk about clean coal without dealing with this problem," says Eric Schaeffer, the director of the Environmental Integrity Project, which just came...
...commemorate the legacy of an Administration with an approval rating in the 20s? As the curtain falls on the George W. Bush presidency, this slim volume unspools a highlight reel of Bush's achievements--from ousting Saddam Hussein and staving off post-9/11 terrorist attacks on U.S. soil to combatting AIDS and malaria in Africa and distributing $16 billion in food aid. Framing the text are stats-laden info boxes, a bullet-pointed list of "100 Things Americans May Not Know" about their 43rd President's record and snapshots of Bush looking presidential (hoisting a bullhorn amid ground-zero...
