Recent history shows it is very difficult for Prime Ministers and Ministers to challenge the internationalist orthodoxy even in a relatively strong and well based democracy like the UK.
I do not buy into silly conspiracy theories that the world is run by a couple of billionaires who enforce their views on world governments. I do observe that there is a very powerful consensus pumped out by most western governments, by leading international bodies, and by many academics and professionals.This consensus can make dreadful mistakes, as it has in economics with the recession machine of the Exchange Rate mechanism ,then the boom/bust of the banking crash and now the rough ride from excessive money printing and inflation to recession again.
Many experts, professionals and officials genuinely believe the consensus they help form. Others have to go along with it if they want to get a job or if they wish to be in the rooms where the conversations take place that shape these things. It is very difficult getting a university science post if you challenge aspects of the global warming story. It is difficult influencing economic policy if you point out Central banks often get it wrong. It is very difficult in the UK to become a government Minister if you consistently advocated leaving the EU. It is very difficult being Home Secretary if you want to stop illegal migration.
The elites interplay with conventional media to constantly reinforce their spin lines. Forecasts and opinions by international bodies and conforming governments are treated as facts. Alternative views and forecasts are ignored or traduced. It leads the populist majorities that form to become more disillusioned with the media as well as with governments. It leads more to then prefer bizarre conspiracy theories.
How many times were we told inflation would stay at 2% however much money they printed? How often were we told when inflation was setting in it would be temporary? Why were those of us who wanted to stop the money printing in 2021 not allowed airtime to put the alternative view?
Most governments pursued lockdown in response to covid, trying to prevent an alternative policy. Most governments claim to want to rush to net zero, though many miss targets or refuse to work to targets applying to them. They usually want to increase the power and revenues of the states they lead.
