If you believe the month-long war in Lebanon is really about Iran's nuclear reactors

We still have United Nations Security Council Resolution 1696 giving Iran until 31 August to suspend uranium enrichment and open its nuclear programme to international inspections. If it does not comply, the council would consider adopting "appropriate measures" under Article 41 of Chapter 7 of the UN Charter, which relates to economic sanctions. Don't hold your breath. Remember how many deadlines lapsed before Iraq suffered consequences. Anyway, we'll see.
