Putting your flag on every thing is a sign of lack of confidence - new nation have the flag EVERYWHERE - old one know who the are and don't need it
Think Norway - only been independent for just over 100 years - flags everywhere - the UK - Netherlands - Italy - not so much
The brits don't even put their name on the STAMPS for heavens sake - because you were first - everyone else had to play catchup.... same as in so many sports and other things - THE Royal Academy, THE Geological Society, THE NATIONAL GALLEY - no reason to add "london" or "Britain" is there.......................
