I don't get why people like you think the world is so US centric. The world doesn't give a flying fuck about giving Trump a very slight lower chance of getting re-elected, much less kill their people and their economy for it. I don't see how studies across the world were fabricated, there's no reason for, say, India to kill millions of their citizens and destroy their economy by faking studies about HCQ when they don't hate Trump and may have even liked him.
You're the one that's confused, here's an analysis on HCQ from someone that has worked on drug discovery for decades.

You're a not a drug researcher.
And I don't think Trump pushed Ivermectin? If it works so well as you think, one would think the Democrats would be all over it so they can say Biden cured Covid and restored the economy.
