Explains / explained

"Professor Johnson suggests in his recent book that it was the harsh conditions of the Russian winter that explained the defeat of Hitler's army in 1942."

Should I use 'explained' or 'explains' here? My feeling is that if I read 'explain' as meaning 'be responsible for' then I should use 'explained.' On the other hand, I was wondering if I could understand 'explain' in the sense that we as present day observers are trying to 'explain' Hitler's defeat; hence the present tense.

Thank you.
