Agreed. I'm not saying that World War I (the major war for Tolkien) didn't influence the Hobbit, merely I'm pointing out that it occurred before either work was written, and so cannot be held accountable for the differences in style.

As for World War II, although it occurred during the writing of the Lord of the Rings, I would not hold it accountable either, as it was apparent from a very early stage of the writing of that book (before War broke out or had become truly bad in Britain) that it was destined to be much darker and deeper.
