King, can you review your response on this. If Germany doesn't have the convoys to trade with Veneuela or Siam, then it doesn't have the transport capacity to trade with Norway.
But as I understand it...
1. If belgium was making the trades instead of Norway, then Germany can get the resources with 0 convoys.
2. If Germany has the convoys, it may still be beneficial to trade with Sweden (since they are neutral) because germany can protect its convoys on a Sweden to Germany path, but can't protect a Germany to Venezuela path. Sweden can trade with Venezuela without fear of US/GB ships destroying their convoys since they are neutral.
