British Vs American Manners

Do the British or the Americans show better manners? I would like to discuss "English" politeness in the context of the British vs the Americans. By "Americans" I imply the USA and possibly Canada.

It was Mr Blair who said prior to the 2003 Invasion of Iraq that "by nature" the British were a "peaceful people". He was probably wrong. A famous Kabbalist teacher I had the privilege of knowing has said (in his book - Wielding Power) "It has been said that the Anglo-Saxon race keep a tight rein on their emotions because they are a violent people and the violence lurks just below the surface" - this is why they need "manners" to oil the frictions in potentially violent human interactions - "Any highly structured society has warring elements that interact in specific ways to maintain the greater whole".

Simply take a look at the UK legal system which has been adopted in the US. You have two advocates fighting it out between themselves and the one to convince the judge or jury in the debate wins. Consider also the UK Parliament, two (OK 3) parties, the ruling one against the principal opposition - in constant war for the electorate - now popularly replicated in many forms the world over. Adversarial statesmanship and law is the norm in the UK and she has handed it over to the USA. Not everyone in the world operates in quite this way.
