Democratic presidential front-runner Hillary Clinton, returning to the stump in New Hampshire on Sunday, mocked Republican presidential candidates for having a “particular fixation on blaming President Obama and me for everything that happens in the world.”

“They’re back to the Crimean War, and they’re on their way to the Roman Empire,” Hillary said during a town hall meeting at Gilbert H. Hood Middle School in Derry, New Hampshire. “The fact is, if you don’t have a foreign policy, you don’t have much to say except to try to criticize the other people.”

Hillary went on to offer an assessment of the GOP’s foreign policy, which consists of: “Number one, send American troops anywhere at any time to do something and, while you’re at it, bomb something – preferably carpet bomb, whatever that means. Or, don’t do anything.”

As to her foreign policy approach, Hillary plugged her recent book, Hard Choices, to highlight her successes as Secretary of State, which included imposing crippling sanctions on Iran and brokering a ceasefire between Israel and Hamas. “I sent them all a copy of my book with a little note saying, ‘You may want to read about how you put together crippling sanctions on Iran in order to get them to the negotiating table to put a lid on their nuclear weapons program. You can read about it. Or maybe you could read how you negotiate a ceasefire to stop rockets from Hamas attacking Israel,'” Hillary said.

“I didn’t get one thank you note back,” she joked.

Meanwhile, Republican presidential hopeful Rand Paul said on Sunday that it is Hillary Clinton that, if elected president, will drag the U.S. into war in the Middle East.

“It turns out that probably the most likely candidate to take us back to war is Hillary Clinton,” Paul said during an interview on told NBC’s “Meet the Press” program. “The interesting thing is while Obama gets blamed for not intervening enough, he’s actually intervened quite a bit in the Middle East and not to our benefit. The Grahams and the McCains have been on the same side as Obama. They just want more of what Obama’s been doing.”
