No strategy is airtight and defeat is always a hairsbreadth away and I don't disagree with your assessment about the relevance of orthodox Leninism in the modern era, I was being charitable and indulgent so the local lemmygards don't throw a fit
But I disagree with the strategy not being clear, I base my assessment on empirical results and ironclad conditions; the military power of the United States is overwhelming on the domestic end, socialists are hard locked into a legalist mode otherwise it's prison or death, third partyism is a solid dead end for the left and has been for 75 years, Kshama Sawant eating shit is another data point confirming that
The immediate goal of the American socialist left should be the destruction of the two party system, the thesis is simple; socdems win elections under the empty democratic banner which leads to the neolibs pushing the self-destruct button on the party, "The centrists will always scurry back to being fascists as soon as a Dem get elected"
This results in the mass disillusionment of millions of liberals and makes third party bids viable as the former democratic base will have to desperately search for an alternative, THAT IS the window of opportunity for an independent worker's party to emerge
For this strategy to work it requires socdems to win elections and remain popular afterward, Mamdani provided a useful template in that regard
And for both the socdems and neolibs to act according to their nature; socdems will remain naive and idealstic and never see the sucker punch coming, the neolibs will remain ideological fanatics who will not tolerate a return to Keynesianism and will sacrifice the two party system to gurentee it never happens
This isn't the Golden Path, but it's the best articulable roadmap I've yet seen accounting for current conditions, unless anyone else has an alternative plan?
