Terrorists do not actually need nuclear weapons. They have been conveniently supplied with 103 nuclear power plants scattered throughout the United States (438 of these deadly facilities exist throughout the world). A planned meltdown at one of these facilities would make the World Trade Center attacks seem like child's play. The massive concrete containers protecting the reactors are not strong enough to withstand the impact of a jumbo jet.
