The OP deals with Chemo, Surgery and Voom - which means that almost anything is fair game for discussion.

Bob: I decline, as a retired gentleman, to be drawn into a discussion of "joint and several liability" (a rather primitive legal construct; better replaced by comparative fault and comparative causation).

But, seriously, strategic interaction (e.g., direct and indirect strategies; sequential and cumulative strategies) applies across the board to any armed conflict.

More later.
