Ron Paul says more people are thinking like him

Speaking at his Iowa campaign headquarters located next to a Quizno's sandwich shop in an Ankeny strip mall, Paul said war is a drain on the economy and it's an "economic fallacy" that such engagements can pull a country out of a depression.

"If a person is a conservative and likes limited government, it's during wartime that government grows," he said.

International aid can do more harm than good for allied nations, Paul said. He said the recent incident between President Barack Obama and Israeli Prime Minister Benjamin Netanyahu is evidence of that.
