Two leading Republicans have begun an unusually personal war of words over foreign policy, highlighting a broader divide within the GOP over international affairs in one of the first public clashes of the Republican Party's presidential primary process.
Kentucky Sen. Rand Paul on Monday lashed out at his Republican colleague Texas Gov. Rick Perry's weekend charge that Paul's "isolationist" views are dangerous. Paul, a tea party favorite, responded by taking a swipe at Perry's fashion accessories in an article published in Politico Magazine entitled, "Rick Perry is dead wrong."
"Apparently his new glasses haven't altered his perception of the world, or allowed him to see it any more clearly," wrote Paul.
Paul continued: "With 60,000 foreign children streaming across the Texas border, I am surprised Governor Perry has apparently still found time to mischaracterize and attack my foreign policy."
Both men are seriously considering running for president in 2016, but the Republican-on-Republican attack is rare so soon before the GOP primary process begins. While Paul has already begun to hire staff in early voting states like Iowa and New Hampshire, presidential candidates aren't likely to begin campaigning in earnest until next year.
With conflicts escalating across the globe, foreign policy is poised to become a key issue in the race - especially as the GOP begins to embrace a libertarian shift on national security and foreign affairs.
Paul has emerged as a leading voice among conservative activists who favor a dramatically smaller U.S. footprint on the international stage.
Perry and others, including Florida Sen. Marco Rubio, support a more aggressive leadership role for the United States, despite polls suggesting that voters have grown war-weary after prolonged military action in Iraq and Afghanistan.
The intra-party split caught the attention of former Vice President Dick Cheney, who offered a warning on Monday for people who might be tired of war or "don't want to be bothered."
"There is a growing, emerging threat to the United States," he said at a Washington event hosted by Politico.
"And in terms of trying to deal with it on a global basis, we're the only ones who can lead that effort. Nobody else can, nobody else will."
