The tournament draw has placed Wales and co-hosts Canada on a potential collision course in Group B at the 2026 finals next June.
But Bellamy was adamant that any off-field sub-plots are irrelevant until Wales secure their place.
"You don’t want to get too far ahead,” said the Wales manager.
“My whole psyche goes back to Bosnia. Bosnia is the most important. If we don’t, it’s done," he emphasised, underlining that the play-off semi-final in Cardiff on March 26 is the only priority.
Should Wales win, they will host Italy or Northern Ireland for a place at the finals five days later — a quick turnaround Bellamy says requires planning without distraction.
"But there will be a game plan for Northern Ireland and Italy as well because of the turnaround.
“If you don’t, then suddenly you get through and then you have to work on this one.
“The simple fact is, whether we win or lose, we’re going to play the other one anyway. So it’s part of the turnaround, to be able to work with the intensity we want to have."
Only after that, Bellamy insisted, can anyone think about Canada — and about Marsch.
The pair’s needle dates back to Canada’s 1–0 friendly win over Wales in September, when Bellamy took exception to what he saw as excessive celebrations from Marsch and his staff.

His post-match parting shot — "I hope I see you at the World Cup" — lit the fuse, prompting Marsch to dismiss the whole episode as "ridiculousness".
With the draw now making a Wales–Canada group-stage meeting possible in Toronto on June 12, Bellamy was asked again about the tension between the two camps.
"We’ve got to get there first but, if that is the case, then we’ll definitely have a nice conversation before that," he said.
Bellamy insisted he holds no personal animosity, while acknowledging Marsch’s combustible style.
"I’ve got nothing against that guy, by the way, I think he’s got something against the world.
“There’s a part of me that really likes him from afar without really knowing him. But some of the things he says, you see his interviews before the other games after playing us…I think I find him very interesting."
He did, however, stand by his frustration over Canada’s behaviour with their early celebrations in Swansea.

"All those wind me up, I’ve got to be honest, they all do. Be respectful.
“It’s not about the opposition, that’s part of the game I see through. It’s maybe more for TikTok or Instagram. I’m not a dinosaur, trust me. I’m not like old-fashioned, but there’s a level of respect."
But Bellamy was crystal clear: none of that matters until Wales take care of business.
For all the talk of a possible showdown with Marsch in North America, Bellamy reiterated that the path to the World Cup begins — and could end — with Bosnia at home.
