Good point.
I found out something else today that I didn't know before, something related to the point of attacks on production facilities. One of the reasons why Hitler wanted to seize control of the Ukraine was that the USSR was able to use bases in the Ukraine to mount air attacks against the Romanian oil production facilities. The USSR was very well aware of how critically short of oil Germany was because of the emphasis Germany had placed on obtaining oil from the USSR in the period between Germany being cut off from oil from the USA and Venezuela and Germany invading the USSR.
I think the US used some of those Ussr bases for their bombing raids also.
