At this point it’s safe to say it was just a display of military might, nothing fundamentally changed in Venezuela.

Is it still sovereign?

Yes

What about the Maduros?

They are kidnapped by the US empire. Now, the battle for their freedom will be a diplomatic and legal one(this will depend highly on the support of our comrades in the USA).

Who is in charge there and are they kowtowing to the United States, doing a bit of both (their own thing and pacifying the United States), or are they resolutely against USA influence?

All of the political structure remains intact so there was no regime change. What they are doing is what they have always done when Maduro was in Venezuela which is to negotiate with the empire. It is the only viable way because the actual material conditions does not allow for an aggressive confrontation of any kind.

Are there still air strikes?

Fortunately no BUT there is still a naval siege in Venezuela. The USA, like a pirate, is stealing oil tankers off the coast of Venezuela.

Edit: typos

Is it still sovereign?

it looks like it

What about the Maduros?

still kidnapped in usa, trying to defend themselves in that kangaroo court

Who is in charge there

delcy, the vice-president

and are they kowtowing to the United States, doing a bit of both (their own thing and pacifying the United States),or are they resolutely against USA influence?

it seems that removing maduro from venezuela didn’t end chavismo, ruining the gringos plans, and they’re in some kind of impasse with some oil stealing and chavismo still in power…in a side quest, corina is making anything that she can to be chosen as the american viceroy
