Sarah Palin has redefined US foreign policy and put YouTube under a little bit of strain by telling right wing radio host Glenn Beck that America must stand by its North Korean allies.

Palin, sometime Alaska governor and current reality TV star, was responding to a question from Beck about how she would respond to a developing situation like that in North Korea.

The Tea Party's favourite cupcake showed exactly what she'd do, ie, engage mouth and let rip before taking her foot off the brain brake.

After rubbishing the current White House for showing a complete lack of backbone, she declared: "Obviously, we've got to stand with our North Korean allies."

Beck subtly corrected her - it's South Korea that is the US client - and Palin appears to have managed to make it to the end of the interview without further rewriting the US's 60-year commitment to protect South Korea - a commitment that cost it some 34,000 troops.

The clip was instantly all over YouTube, leading to apparent download delays as worried Americans try to work out exactly whose side Palin is on.

It nicely rounds off a week that saw Palin slapped down by former first lady Barbara Bush, who described Palin as very beautiful while hoping "she stays there (in Alaska)". Palin also got a sound bludgeoning from animal lovers after she clubbed a fish in her TLC programme about her Alaska. ®
