You don't have to agree with any :)
I think the idea is to drive everything to ruin. I don't think it is just him. There are lots of smart people telling him what to do.
On the wine front - not all are bad from the US and some are really good. But there is better on average elsewhere. History plays a big part in that for sure.
I honestly don't think he really cares what happens. I think he has a long game that benefits him and all the chaos that happens in between now and then is just an afterthought for him.
I agree. Everything is for his own gain/ego - no one else matters.
