As for the US cultural domination, I'll just say: guilty as charged. I've been living in the USA for a number of years and I've been following US politics since then. So I may have a skewed view of what the right balance "should" be on ET.
For what it's worth, I too would like to see more coverage on European issues and countries -- outside France, that is. Europeans think a hundred miles is a long way. Americans think a hundred years is a long time.
