1) Do nations and/or cultures have a right to defend their cultures against erosion or assault? What domestic measures are reasonable in this matter?Well, the best definition of culture I ever heard was used in reference to the culture of a business, and was simply "the way things are done around here". In that context, where the senior management decided on a change of business strategy that required a cultural change to match, the rule of thumb was that it always takes a minimum of SEVEN YEARS to change the culture of a business. Businesses, by their nature, tend towards a much more rigidly defined and hierarchical structure than any regional, national, or religious culture, without even considering the vast differences in scale between all but the largest companies and all but the smallest cultures.
To use an example close to my own heart, even little Wales, with a definite cultural identity of it's own, has about 2.5 million inhabitants within it's borders, though something likea a third of those don't think of themselves as Welsh (mostly they're English or just generic British - a word whose origins mean the same thing as the modern sense of "Welsh" anyway, so we win

); and about half that number outside it that identify themselves as Welsh, be it
Cymru Cymraeg or
Cymru di Gymraeg (that's Welsh-speaking Welsh and non-Welsh-speaking Welsh to you heathens out there). So, about 3 million people think of themselves as Welsh - an order of magnitude more than even Microsoft can lay claim to.
Consciously changing a culture takes a conscious (and, in any open society, open i.e. declared) effort by successive generations of leaderships to change, with the open and declared support (or at least, the lack of opposition) of a majority of the populace. Cultures cannot be eradicated by force - ask the Romans, who found themselves having to adapt their rule to suit local conditions; or the English, who tried for 800 years to forcibly integrate the Welsh, and still didn't manage to remove the Welsh culture entirely.
Certainly, Welsh culture changed beyond recognition in those 800 years, but how much of that was down to conscious English efforts and how much down to simple economic disparities and general political, social and technical advances that changed England itself by the same degree? Without having a clone of the planet and everyone on it with which to operate a control experiment, we cannot know.
And the efforts of Welsh nationalists and culturalists to reinvigorate Welsh culture, specifically the language, took over a century, from their origins in Welsh non-conformist religion and ideas like Chartism, of constant pressure and campaigning, before the Welsh Language Act was passed in the early 1970s, making Welsh language teaching compulsory in Welsh state schools and creating the bilingual roadsigns that tourists find so impenetrable.
So it is possible for a minority to conscisously change a culture in a particular direction, but the pressure has to be sustained for many years, and has to be moving in a direction that is not resisted by the majority. You can change a culture against a resistant minority, but the timescales involved are so lengthy and the results so unpredictable that you might as well trust to the natural shift over time to accidentally favour you.
Christian missionaries in Northern Europe found that out. That's why the many churches were founded on pagan sites. It's why the festival to mark the birth of Christ got marked in midwinter with feasting, holly, ivy, gift-giving, and drinking. "Wassail" is an Anglo-Saxon word (when the A-Ss first arrived, they were pagan, and the Celts were Christian). It's why we eat chocolate eggs at Easter.
And Muslim invaders found out the same thing in North and Central Africa when they conquered there in the few centuries after the foundations of their religion. Female "circumcision" was and is practised across the region by more or less everyone, regardless of their religion. Somali or Sudanese Christian girls are no more or less likely to be genitally mutilated than their Islamic playmates, because, in the culture they live in, female genital mutilation is "the way we do things around here".
They also found it when they invaded Northern India, and found that the people there had such a strong sense of family honour they would kill members of their own kin if they were seen to have transgressed in any way, and such a view of women that they would be married off against their will as part of property transactions, something that had died out in Europe in the Middle Ages. This was not unique to their converts, but also happened among their neighbours the Sikhs and Hindus.
2) How do we measure a culture's "inferiority" or "superiority"?Tricky. I like my culture better than most others I've seen, though some have things I wish we did more of, and some have things I'm glad we don't do.
I like the way Americans treat one another with politeness, but hate the way they see guns; I like the way the French do food, wine, and family, but hate the way they do business; I like the way Sri Lankans smile all the time, in spite of anything that might happen to them, but hate the way they tolerate all sorts of corruption even while recongnising it as wrong; I like the way Pakistani Muslims I've known can be so humble and friendly most of the time, and I hate the way they can become so angry and blind to argument at the drop of a hat whenever they feel slighted in any way.
Ultimately, I think ideas of inferiority and superiority conform to the same inverse "as above, so below" rules as most aspects of humanity. I like things in my own behaviour that I personally think I am good at, and dislike the converse behaviours in others. I dislike things I am bad at, and admire other people who are better at them than me (or, sometimes, feel jealousy and contempt for them). Scale that up to a national, tribal, racial, or other large-scale level, and you get a culture.

...but I see no reason for the US or the UK to worry about its future. Cultures can remain distinct, in contact, and in peace so long as advocates of "cultural superiority" are held at bay.
Its true, the UK and USA will no doubt survive, as
states. But we are debating
culture here, Not nationality. What will it mean to be British in the next few decades? Will Britain be a land of peace and harmony or will it become a fractured nation ridden with the same conflicts which today characterize Lebanon?
Oh for the sake of an historically-uncorroborated Jewish religious leader of the early first millennium (Common Era) - the introduction of the
mobile telephone has changed British culture (and landscape - there are hundreds of times more mobile masts here than there are minarets) more in the last 10 years - e.g. we now talk on commuter trains (just not to one another) - than the Muslim and multiculturalist boogie men you are so paranoid about have in the last 1000.
Britain is as likely to turn into a free floating island that can be towed around the world wherever the ocean currents permit as it is to turn into anything approaching the Lebanon.
I know you don't like the BBC and you felt unsafe walking the streets when you lived here, and you feel something akin to betrayal when British newspapers didn't bother publishing some badly-drawn and unfunny political cartoons which everyone who wanted could see on the internet anyway, just like I did - that's how I know they weren't funny.
Why don't you just have done and make yourself a sandwich board with "The End Of The World Is Nigh" written on it? Or maybe a cute little chick costume so you can run around the farmyard predicting the imminent collapse of the firmament every time it rains? If you've nothing constructive to say, you might as well, you know.
Oh, and you can get off your high horse on the cartoons thing anyway; I didn't notice the whole of the Danish literary world publishing their own novels insulting Islam or digging into their pockets to contribute to the security of Salman Rushdie when
The Satanic Verses were published, as the British were "supposed" to when cartoons thing kicked off. I daresay there were even some comments in the Danish press at the time - if it was even covered - along the lines of "well, it is a bit offensive" or "duh! what did you
expect them to do?". This wasn't evidence of Danish cowardice or that Danes were some sort of unconscious Islamicists; it's just that the duplication wasn't necessary.
