There are certainly parallels with the 30's, but I see different ones than you do. For example an extremely dangerous American president who's only interested in money and trade and hasn't got a clue about what's really going on, the Russians trying to destabilize other countries in order to make advantage of the confusion, the Chinese forced into a confrontation because they are becoming too powerful and too successful and last but not least a weak and divided Europe, that needs to understand they are on their own in a world gone completly ballistic.
