Why is Uranium such needed source for nuclear weapons? Why hasn't there been a through investigation of nuclear bases such as the one found in 2003? Can we deter Iran from using nuclear weapons or is violence another solution? Can we tolerate Iran joining the world nuclear club, like we do with North Korea, and Pakistan?

If we were to deter Iran from using nuclear weapons, then what ?
 * Viewpoint:** I believe that the Uranium give back as fuel only useable by civilian nuclear facilities would help undermine the nuclear ambitions and plans of Iran.
 * Rationale:** Why isn't the US making an effort to alleviate the nuclear dilemma?
 * Assumption**: If Iran were to initiate a predicament regarding the Uranium turned in to fuel not useable for nuclear efforts, then we would find that Iran isnt using the uranium for medical or civilian purposes.
 * Implication:** If Iran keeps progressing with its clandestine nuclear programs, then that would take precedence in world issues, as nuclear threat.
