IMO it can always get worse. You can look to Ukraine and the Philippines as examples of just how bad it can get; at least for now they (Serbia, Hungary, Slovakia, Moldova, Georgia, etc) are ostensibly independent countries with some sort of self-interest and self-preservation.

It's one thing to have a Franco or Salazar in power, and another to have a Horthy or Quisling. And there are all sorts of creative things the west can use a fully compromised Serbia, Hungary, Slovakia, etc. for (alongside the fact it would strengthen the western unified fascist front in the likely upcoming WW3), as can be seen with the Kenyan military police in Haiti, or the US'/western EU's attempts to expand NATO activities to the entire globe (in Asia and west Africa in particular).
