On a tangent: This hacking of parler might be the reason a more recent WW does not come into fruiton.

But it is, as is WW I. The latter ended 102 years ago and set in motion many of the technological developments which define our current world, WW II refined these to a level which is recognisable and often still useable today. Electronic warfare, programmable computers, jet-powered aircraft, nuclear weapons - all of these were used in WW II. Modern computers are faster, modern jets are more reliable and more fuel efficient, modern nuclear weapons are more compact and modern electronic warfare has kept up with the development of computers and electronics but as wars go WW I and WW II were the first - and possibly last [1] - "modern" large wars.

[1] - modern weaponry makes large-scale land war difficult to survive, e.g. the average survival time of a main battlefield tank is counted in minutes.
