The first time I know of the symbolism of the 'yellow ribbon' was the Tony Orlando song 'Tie a Yellow Ribbon...'round the old oak tree' (don't know if you're old enough to remember.
It's supposed to be a sign to a loved one that love is still waiting for them at home.
Made slightly more popular by the Viet Nam war...oops..conflict.
Considering how evil that 'conflict' was and how far the tentacles of the conspiracies permeate, this seems like another innnnnteresting 'coincidence'
