Why do you think FIFA World Cup will have an effect? Remember boycotts and sanctions during the beginning of the war? Did it help? Did banning Russian athletes help to end the war? Besides, WADA has banned Russia for 4 years in 2019 for participating in any sports world championship events. Even before the war started, Russia did not take part in qualifications. Which means they dont care about this FIFA World Cup.
There is lot of nonsense in your post. Sanctions - it have effect, but not enough. BTW, what you're offering? Continue business like nothing didn't happened and fund war? Yes, WADA banned Russia, but until war their athletes were allowed to participate in competitions under neutral flag. Same applies to their national football team. They participated in qualification and had to play game against Poland. And when they got removed, judging from reaction in Russia, they were really butthurt about this decision.
