Worst Relationships between Heads of Friendly or Allied Countries

Jimmy Carter and Helmut Schmidt didn't go along very well and SPIEGEL ONLINE had an English-language article on that a couple of years ago:

Dubya/G. Schröder may count as well even though that largely happened due to Schröder's face-heel turn, going from strongly supporting military intervention in Afghanistan to strongly opposing military intervention in Iraq within 12-month-timespan or so.

Wasn't a face-heel turn at all. It was two completely different situations that did not warrant the same reaction.

Sorry, should have written perceived face-heel turn...

Talking of Angela Merkel, I gather her relations with Mr Silvio Berlusconi weren't too great.

Is it even possible for a female head of government to have a good relationship with Silvio Berlusconi for that matter?

I mean, the man is a pig. Imagine Hillary would become president and meets Berlusonci. The first he'd probably say is: "Madam President, may I grasp your breasts?"
