These are my beliefs:
- Workers should control where they work at and receive proper equity from the value they create.
- Non-essential industries should not be controlled by the government, essential industries should be, for the most part.
- People should be able to have some say in who gets into government positions (at a minimum, like Vietnam or Cuba).
- Social democrats are not the same as fascists.
- Regular people (non-politicians, pundits and/or wealthy people) who happen to be liberals are likely well-intentioned and could be educated.
- Military action should not be taken unless you are being directly threatened by another country.
Should a socialist country provide aid to a revolution in a bordering country?
In most cases, I would say so. It depends on how strong and serious the movement.
I think an attempt could be made to work with the existing government, but, if the revolution is strong and more aligned with you, it would make more sense to actively support them.
But this turns into "interventionist" behaviour quite quickly. Is a "permanent revolution" attitude justified?
The Soviets aided their fellow SSRs (who often had independent socialist revolutions), and then drove west, hoping to overcome the Sucdem/Nationalist Coalition in Poland and link up with the KPD. Cuba famously aided Angola.
