According to Israeli intelligence, cyberattacks and malfunctions were only part of the reason for the deceleration.
Israeli Prime Minister Benjamin Netanyahu wasn't afraid to get dramatic at the United Nations last year when, in a speech about the dangers of Iran's alleged nuclear program, he used a prop. Two, actually: a chart and a red marker. In case the seriousness of the threat wasn't clear, Netanyahu had done the math -- and showed his work.
The prime minister's appeal was practically made for contemporary Web journalism (Iran's enrichment program, IN ONE CHART) but it's also been the focus of some pushback. Netanyahu faces a growing coalition of Israeli security officials who believe a preemptive attack on Iran would be ill-advised, if not disastrous.
