There are 40,000 Americans living and working in Arabia. There are a number of ex-pat and annuitant and US student websites.. They don't report any difficulties.. My experience isn't unique.
I don't know that much about India.. I know the Arabs traded with the Indus Valley long before Islam.. and I know the British Empire controlled a lot of people with a small force by setting one group against another.
What do you mean by 'they don't report any difficulties'? Do you think that means there ARE no difficulties?
I had dinner with an ex-pat who lives there tonight. Not American, but western.
