I originally got an MD from an EU country, and I'm currently working in the US as a postdoc (doing research only, not clinical work). I was lucky to get this postdoc position without the need for a PhD, as in the US an MD and a PhD are both considered terminal degrees. Further, I seem to be on my way to get a US tenure track job in the next couple of years.
My question is: if I ever decide to move back to the EU, can I get a faculty job without a PhD? I know most EU countries have stricter requirements (i.e., absolutely need PhD) than the US for faculty positions. Can the US postdoc + hopefully tenure-track job bypass the bureaucratic requirements and be recognized as equivalent to a PhD?
