You said earlier the europeans didn't do any fighting? make your mind up!!!
The point you have spectacularly missed is you don't need all this logistical and military hardware to defeat an enemy that do not have these things, The US and other forces couldn't adapt their fighting strategy, which is why i talked about Nazi troops in 1939... they were very successful against nations stuck in 1916, that changed when the allies adopted modern warfare and Hitler attacked the Soviets.
You also fail to appreciate that the UK has a small military, would be incapable of mounting a task force to take back the falklands, if that proved necessary, has less front line ships than Japan, could only provide a handful of planes to bomb Syria.... we are like the rest of Europe/nato, totally dependent on the USA.
However, my point is that can all change, europe has the money, industry and expertise to re-arm, if the US/UK/canada pulled out of NATO and they could do it very quickly too, the UK withdrawing would be a huge mistake, its our continent too and what happens there will always very much involve the UK.
