People used to claim Aus & NZ weren't interested in hosting the World Cup. Despite all that, they were persuaded otherwise and it came to pass in 2008. So, we have to persuade them now that a regularly scheduled GB Lions tour down under would be a worthwhile experience for their players, fans and broadcast partners, and also be financially viable too. Not as a replacement for the World Cup or Four Nations, but in addition to it. The international calendar can be made as flexible as it needs to be, if the necessary will is there.
Or we can just give up, of course.
We don't give up, and that is what a lot of this 'bring back GB' stuff is about. We persevere. Okay, so England are not world beaters at the moment, but I cannot see how incorporating non-English players into the squad is going to improve them in any case. What the current situation highlights more than anything is that the system for producing world-beating English players is still not up to the job - that is where the effort needs to concentrated, not on any identity issues. And, of course, that the development of rugby league in the other home nations isn't as easy, or as rapid, as some thought it would be.
Much easier, then, to withdraw into the laager, circle the wagons around the heartlands (yet again), and not have to bother with all this 'development stuff'. Pretend that we're Great Britain (even including a completely separate state that has nothing to do with GB), that the game is, in fact, spread throughout these islands, and go back to the mediocrity that we enjoyed in the 80s and 90s. Forget these rose-tinted glasses that imagines heroic battles - it was a bloody miserable time where any success was tempered by the realisation that we were going to get stuffed in the decider (and, often, success was managing to score a try in some games/series).
No, for once in its existence rugby league needs to look to its future, not its past. The game needs to be developed in all parts of Britain and Ireland. England, as the standard bearer, needs to create ways of producing players good enough to not just compete with, but beat, Australians and New Zealanders. The other nations need to overcome the difficulties and setbacks they face to produce a higher standard of football. It is not easy, and it hasn't really been tried in the history of the game, but it is the only way.
