I suppose as a member of the club known as "not Americans", I'll give you a recap (Disclaimer: I read too much Guardian).
Our good friend has so far:
-Suggested the Olympics has issues on foreign soil, breaking the cardinal rule of "never shit on your host's door" (actually this seems to be what Krauthammer is most pissed about, since as a successful businessman he should know this). Prompts comebacks from the PM of the UK and the Mayor of London,
the latter in front of a 60,000 strong crowd.
-Referred to the back garden of 10 Downing Street as the "backside"; implicitly referring to David Cameron's arse.
-Revealed he met with MI6, the ultra-secretive Intel organization that no one, NO ONE, volunteers to have met.
-In Poland, aide told journalists to
"Kiss my ass" after Mitt refused to take questions during a visit to Poland's equivalent to the Tomb of the Unknown Soldier.
-In Israel, his speech that "culture" was the reason Israel's GDP was so much higher than Palestine
prompted accusations of racism.
This off the top of my head. As well as the confusing insistence that Russia is America's number 1 geopolitical foe is just, really, really weird.
