The head of Israel's National Security Council said Saturday that despite Iran's announcement that it had enriched uranium it was not too late to stop the Middle Eastern country from developing nuclear weapons. Giora Eiland told Israel Radio that Iran was trying to create an inaccurate impression of inevitability about its nuclear program. "True, they somehow upgraded their ability and have achieved new abilities of research and development in uranium enrichment. But between that stage and having the commercial ability to produce uranium in amounts needed for a bomb, and between this ability and creating a system of real weapons, there is a gap of technology and time," he said. Eiland spoke after Iranian President Mahmoud Ahmadinejad opened a conference on the Palestinians by calling Israel a "rotten, dried tree" that will be annihilated by "one storm." Eiland declined to respond directly, but said: "I hope the world understands his words in their full seriousness."
