i didn't hear anyone in Qatari channels complaining from any discrimination against their team in the tournament , problem of fans AFC was aware of it before the start of the tournament , so it's their fault that they didn't force UAE to host QATARI fans , which wouldn't have been many anyway , they don't fulfill their stadiums or even get close to this , so i don't think it'll be world war III , it's just a game , referees would interfere or not , i'm not sure about this , but maybe with VAR every team would get their rights
