Does Roosevelt receive the bonus political alignment marker only when advancing or debating the Global issue (and it resides in a UK or USSR space) or does this kick in regardless of the issue he is played on as long as board conditions are applicable?
No an attribute that says If (issue) should always be interpreted as: If played on the Global issue that resides on the UK/USSR track, etc.
If you play Roosevelt on any other issue whether the Global issue is or is not in play and in that location, you do NOT get the bonus.
I will be adding this clarification as you are the second person to ask it.
Sorry for the confusion,
