Looks like if Germany don’t DOW on USSR but leave one of their subs in SZ125, even though Italy does DOW, then USSR loses the lend lease bonus.
Rule:
“5 IPCs if the convoy in sea zone 125 is free of Axis warships, Archangel is controlled by the Soviet Union, and there are no units belonging to other Allied powers present in any territories originally controlled by the Soviet Union. Theme: National prestige and access to Allied Lend-Lease material.”
Has a clarification been issued on this point? Reading the rule text it seems that a nation not at war with USSR can affect their NOs, which is counter intuitive.
