1) Do cloth masks work or have any value? Trivial to google. https://pmc.ncbi.nlm.nih.gov/articles/PMC7510705/
2) Do you honestly think that 124 people have died to prop up science funding?
If so, can you think of an easier way for US researchers to advance their evil plans and secure funding than having these people in a completely different country die and that country's health authority raises concerns in the media? I mean, even if that is the plan, don't you think that's a bit subtle and ineffective to convince a highly conservative; conspiracy theory friendly US administration to fund science?
To gain power and influence you need to state your position and stick to it. New evidence to the contrary? Reiterate and double down on your position. Attempt to discredit the evidence. Having people die doesn’t matter as long as you stick it out.
The last thing you should do is incorporate new evidence and change your mind as a result.
The (people who want science funding in the US) manipulated (another country's health authority) so that (Donald Trump and RFK would give them science funding), because both are known particularly to be influenced by the CDC equivalent of the Congo.
