Hi John, I'm not sure I understand the question.. If you are operational in multiple markets - EU and US, then you should have each region setup with its own local transit and peering, and in the case of transit you should ensure that each region has redundant transit feeds.
What you don't want is 1 feed in the US and 1 feed in EU and then to have your whole traffic trombone over the Atlantic should one of the feeds fail. Similarly, you probably don't want to have only one feed each with transit A and transit B in EU and the same again in the US.. you don't want a failure of A in EU to cause all traffic via A to be preferred via the US. Build each region with external connectivity as though it is autonomous and then putting a decent level of redundancy on the internal connectivity (multiple transatlantic routes) will give the best network setup for most use cases...
