It's a term for overly enthusiastic Indians that we are no longer allowed to use directly. It comes from a popular Indian chant.Zero-Covid was the right strategy in 2020, probably even most of 2021. However it's 2022, and it's probably time for a new strategy. I don't think it's a matter of refusing to accept mistakes. I don't think there is a clear consensus on how to move on. That being said, it should be more of a scientific decision at this point rather than political.
With regards to the brain-drain. This is the US' own self-inflicted gunshot wound. Everyone with half a brain knew their xenophobic anti-immigrant policy drive is leading to this outcome. For 50 years (basically since the post-80's opening up), only foreign universities were worth going to for graduate studies and the US was the best. Then in the 2000's there was that crap with Wen Ho Lee and has only gotten worse.
Pardon my ignorance, but what is JH?
Those troglodytes on twitter talking about "real vaccines" are really something. They don't even realize that many countries have already reopened fully while relying primarily on Chinese vaccines. If they are so ignorant on something like this, why do they expect people to think they are correct when they assert that the US/West is the shining beacon of freedom and democracy for all the world to follow?
I don't mind their ignorance. What's some cope rage compared to the massive human and healthcare cost they suffered only for their economies to still be worse?
