How long does this political darkness last?

So I just read that the CIA has been given notice to resign- all members. Of the CIA. Because they won’t align with Trump’s plans. It’s chilling. I’m wondering if anyone can see how long this darkness lasts because it feels hopeless, like the world is sinking into authoritarianism and nothing can save us.

EDITED to say it’s not necessarily about the CIA, I get that they are bad, it’s the abrupt dismantling of everything- the department of education, the entire US public service, USAID, possibly NATO…
