Kevin, most historians do indeed say that Britain had no choice, and I have supplied quotes. Do I need to repeat them?

As for leadership, military historians are overwhelmingly, I think unanimously, of the belief that the leadership was not deficient.
Again I have supplied quotes and can repeat them.

You are entitled to the opinion that the views of historians are not significant.

I accept that they might all be wrong, and if they are then so am I.
Otherwise I am right.

I happy to leave it there.
