This is not a communist perspective.

This is just a national chauvinist perspective.

You’re arguing that the actions of the PRC state made the PRC state safer and more powerful.

Others are arguing that this was done at the expense of the power, well-being and lives of dozens of other communist parties and hundreds of millions of working people they represented. That the PRC may have gained power but Communists as a whole lost it and millions of workers were betrayed into abject poverty and left at the mercy of rapacious capitalist imperialists in the process.

Simply saying “but it worked the PRC state did get safer and more powerful by betraying hundreds of millions of workers to the depredations of capital” isn’t something any communist should be happy with.
