In a column written for Time magazine's annual 100 most influential people in the world, former Prime Minister Ehud Barak offered his thoughts on Israel's current leader Benjamin Netanyahu, whom he describes as " determined, effective and focused... but over time" has learned to equivocate on the most pressing issues facing the Jewish State. "I knew Bibi, decades ago, as a soldier and young officer under my command facing real fire. He was determined, effective and focused. Character does not change. Chickensh-t he is not," wrote Barak. "But over time, while thoughtful and an avid reader of history, he developed a mind-set at once pessimistic, passive and anxious. Benjamin Netanyahu seems to avoid any initiative. Some say it’s all about surviving in power. I think he is more complex and nuanced." Barak went on to write that Netanyahu has failed to engage in Israel's most urgent matters, especially "on the Palestinian question" in which "he grossly ignores the slippery slope awaiting Israel in the form of a one-state solution."Barack closed his short biographical accompaniment to the article by touching on the Iranian nuclear issue, agreeing with Netanyahu's assessment that the Islamic Republic is a serious threat to existence of Israel, and urges him to take bolder action."To leave his mark Netanyahu must swiftly heal wounds opened by his campaign, mend the working relationship with President Obama, fight hard—mainly behind closed doors—for a tougher policy, and even, if needed, an attack against Iran and boldly engage the region’s moderates against terror, radicalism and Iranian hegemony. Daring actions are needed. Not just words."The 'Time 100' is an annual issue that lists the most influential figures in the world. They usually consist of leaders, cultural icons, scientists and array of other figures who impact the world around us.
