Glad to hear. You have refused to acknowledge that the Zero was eventually fitted with both armour and self sealing tanks, repeatedly stating it didn't have these things, but of course too late to have made a difference, which goes back to the issue of the Japanese not acting fast enough, not a fault of the aircraft's. Also you refuse to acknowledge that the Zero was the better carrier based aircraft between 1940 and 1942 out all frontline carrier aircraft, but you have acknowledged that it was far more than your initial assessment of the type, which I guess could be considered progress.
It was a clever design to have met the specification, which Nakajima believed was impossible to fulfil, so didn't bother, although the Ki-43 mirrored the A6M in many ways. It certainly was flawed, but it can be stated that it was expertly executed despite its flaws, which led it to do very well indeed, even unexpectedly so in the hands of highly motivated and highly trained aircrew. Having said that, its merits were not enough to save it as its career grew longer, those flaws becoming increasingly apparent and detrimental to the type, but the final argument about them has to be that the Japanese, again and not for the last time, dropped the ball and failed to get its replacement into service in good time, so it was kept at the front line for far longer than what was intended, exposing its weaknesses time and again.
It's no wonder that the aircraft has, in Japan at least come to symbolise and characterise the entire Japanese effort in WW2 and is held up in some reverence as a result. Not surprisingly, there are museums all over Japan with A6Ms in them.
