This might not be an exact parallel, so bear with me. But I view the position of England's football team in this tournament as being similar to the predicament the Brazil team of 1970 and the Argentina team of 1978 found themselves in: knowing that any succss would be used as an affirmation of a regime.
You can be sure if England reached the final on Sunday and won it the government would exploit it to the full and the about to be massively out of control Covid19 infection rates thereafter will be lost in an avalanche of jingoism.
As said, not an exact parallel, as we dont live under a military junta. But it's not so much of a stretch to be dismissed out of hand.
