President Obama has decided to abandon the Bush administration’s so-called “missile-defense” system in Eastern Europe. The Wall Street Journal reports the White House based its decision on an assessment that Iran’s long-range missile program hasn’t significantly progressed. The move marks one of the Obama administration’s sharpest reversals of a major Bush administration foreign policy to date. The Bush White House claimed the missile system was intended to thwart a potential Iranian attack. But critics widely denounced it as a first-strike weapon for hitting Iran or other targets. Although it’s halted the program, the White House is reportedly open to a revival if Iran’s capabilities improve.
