The JCP supported the Prague Spring and Opposed the USSR.
Remember these are NATOpedia links too. Many of these can be compared to Eurocommunism because many Eurocoms opposed USSR while also supporting Reformism. The JCP can also be compared to the majority of the CPA in Austria.
The JCP is one of the largest communist parties in a non-socialist country that also happens to be a US vassal but it comes at the cost of it being infected with this sort of left-liberalism. Just a product of it’s environment really.
