People are taking about this like it's do'able but it's a non-starter.
There was no boycott of Qatar despite human rights violations, it won't happen here.
But the second Trump tries to involve himself in the tournament, crowds need to boo the fuck out of him and the players need to tell him to do one if he tries to interfere like he did with the Club Word Cup final. A bit of side-eye from Cole Palmer won't be enough this time.
Hopefully the cunt will be history by then anyway.
