Political Issue that I am personally interested in

The issue that I am interested in is the potential for an Iranian nuclear bomb. Iran is a member of the Nuclear Nonproliferation Treaty. They insist that under the treaty they have a right to enrich uranium. Enriched uranium is used to fuel nuclear reactors, but highly enriched uranium can be used to make an atomic bomb! Many nations believe that Iran is secretly working towards building a nuclear bomb, because they have lied about their plans in the past and a secret nuclear facility has recently been exposed. Iran has returned to talks with the U.S. and other countries to negotiate a solution. Some fear that Iran is just using the talks to buy more time for the program and to split off Russia and China from any future sanctions.
I am interested in this issue because if Iran cannot be stopped by talks or sanctions, some countries may attack Iran, who will retaliate by stirring up trouble against our troops in Iraq, where my brother is serving in the army. Also, Iran might unleash its terrorist allies to wreak havoc on other countries. If Iran makes a nuclear weapon, then other countries in this unstable region will want to make their own bombs. I believe that the only solution is containment(threaten massive retaliation if they use the bomb and make things unpleasant through sanctions if they keep the bomb).
