I like it deefer, you admit the UK has differences from the ICAO standard, yet you glaze over that to bitch about the US despite it having the most traffic. Work on your own country. When it moves as much traffic as the US, then talk to me. The UK last I checked didn't even crack the top 10 as far as busiest airports as measured in aircraft operations. France has busier airports.
Fix your own before you feel entitled to complain about the one that moves the most.
