Skepticism doesn't require evidence. The only party that needs to provide evidence is the US who operate these labs. All the following questions need clear answers:

• If the international community's concerns are “disinformation”, why doesn’t the US release detailed materials to prove its innocence?
• What did they spend the $200 million on?
• What kind of research was conducted on which pathogens?
• What kind of sensitive information about public health cannot be shared?
• Does the Ukrainian side know what the US has been working on in Ukraine?
• What is it trying to hide when the US Embassy in Ukraine deleted all relevant documents on its website?
• Why does the US insist on being the only country in the world to oppose the establishment of a multilateral verification mechanism though it claims to abide by the BWC?
• If the US wants to prove its innocence, why doesn’t it open up these bio-labs for independent investigations by international experts?
