- The situation in Russia has become very polarized.

We are back to the days of the Cold War when you look at the world right now, says Wada's boss, Olivier Niggli to SVT Sport.

It was last summer that the conflict between the United States and Wada flared up.

The White House then presented a report in which the United States considered that Wada had not done enough against Russia and the extensive and suspected state-sponsored doping that was revealed after the world's most expensive Olympics, the Winter Games in Sochi in 2014.

- What the United States accuses Wada of is not true.

Without Wada and an international anti-doping cooperation, the great Russian doping scandal would never have been investigated, let alone revealed.

Threat of withdrawn support

The USA is Wada's largest contributor - the country contributes approximately SEK 24 million out of a total of 324. The USA now threatens to withdraw all support if the country does not get greater representation, a proportionate voice, in Wada's decision-making boards and committees.

Wada replies with threats of new rules - that nations that do not contribute financially may not send athletes to international competitions, such as the Olympics.

Fabric about Wada: "Shameful"

The head of the US anti-doping unit Usada, Travis Tygart, tells Reuters that Wada's threat is both false and illegal.

- It is shameful to make illegal threats against American athletes.

There is something wrong when the world organization attacks one of its key partners who does everything to maintain the rules while being blind to countries like Russia that have state-sponsored doping programs.

It's an incredible hypocrisy.

"To the detriment of the athletes"

According to the Wada chief, the action is part of a growing isolationist trend from the United States.

This at a time when the doping problem instead needs cross-border activities.

- Anti-doping requires international cooperation.

An individual country alone cannot enforce its views.

Athletes compete against each other and come from all corners of the globe, and if there is no coordinated anti-doping work, Wada's efforts will be incomplete, which is to the detriment of the athletes, says Olivier Niggli.
