In times like this, it's disheartening to read some of the conversations (not the quoted tweet), where Europeans are gleeful about gaining edge & recruitment opportunities, or Americans suggesting that the US is/was the only place with investment, infra and structures for high-quality science.

And great science has always existed outside of the US too; the US system has been great but not as exceptional as many think. Notably, European research funding is not under a single agency for an 🍎-🍎 comparison to NIH/NSF.
