Democrat Hillary Rodham Clinton advocated talks to settle differences with Iran but said Saturday that Teheran would invite US action if it were to disrupt oil supplies.
"I will make it very clear to the Iranians that there are very serious consequences attached to their actions," Clinton said. The presidential candidate spoke at a town hall meeting that took place in a high school, with 300 people in a Democratic stronghold in early voting South Carolina.
The New York senator, responding to a question, said blocking oil shipments "would be devastating to the world economy."
If the US took military action as a result, she said, "I would hope that the world would see that was an action of last resort, not first resort. Because we need the world to agree with us about the threat that Iran poses to everyone."
