RC20 - No, I am sorry man - introducing the superiority of a semi auto carbine in trench warfare, or the fact that an M1 Garand is obviously a more capable infantry rifle proves nothing in this debate.
The original issue was very, very simple: best bolt action battle rifle, OP thinks it is the SMLE, commence debate.
We are not talking about if a rifle won a war, if it was cheaper to manufacture, if it was more accurate. We are talking about the best implement of battle for an infantry soldier, with our options being limited to bolt action rifles. That the British got kicked out of Malaya does not make the Arisaka a better rifle than the LE - that is a straw man and completely irrelevant. Tactics are continually being confused with the debate at hand. No one has put it into an ideal setup etc - in almost every respect that really matters the SMLE is superior as a battlefield weapon, in those it is not superior in, the inferiority is so slight as to make no practical difference (accuracy maybe).
Your question about when the superiority of the SMLE has been used decisively has been answered, repeatedly, by myself and others. In short, the opening battles of WWI. You then list a bunch of examples of where it failed to be decisive in WWII, and claim that points to something (even though everyone contributing here, yourself included I hope, surely agrees that major battles in WWII were not won by rifle fire) when in fact it is an argument for precisely nothing.
Arguments have been offered as to why the SMLE is the best bolt action battle rifle - no arguments strong enough to stand on their own merits without attempting to confuse the issue have been offered by way of rebuttal.
MJ1 - Mate, I am so very jealous of your rifles. If you have any made in Fazakerley, that is in my home town of Liverpool, where I am now. Hope to get hold of one myself one day, though by the time I am in the position to do so they will probably be like gold dust.
