(NEWS.YAHOO) — President Barack Obama on Tuesday bluntly accused Republican White House hopefuls of recklessly “beating the drums of war” against Iran for political gain while ignoring the potential human costs of such a conflict.

“Some of these folks have a lot of bluster and a lot of big talk,” he said scornfully at his first White House press conference of 2012, but “those folks don’t have a lot of responsibilities. They’re not commander in chief.”

“The one thing that we have not done is: We haven’t launched a war. If some of these folks think that it’s time to launch a war, they should say so. And they should explain to the American people exactly why they would do that and what the consequences would be,” he said. “Everything else is just talk.”
