It is no surprise that every cell would have a different name, with 'peoples', 'popular', and 'liberation' being common words in the name. But then, 'bolshevik' means "majority", so disinformation about the popularity of a cause is nothing new.
Soviet seed money was also contributed to many neophyte environmental groups, seen as a means to hobble, if not hamstring western industry. Since then, much of our smokestack industry has been moved offshore or simply outsourced.
Environmental regulations which go far beyond common sense and commonly present a 'moving' target (the most expensive way to refit a facility is to do so in multiple increments, rather than in one sweeping refit) have taken their toll.
With the US giving up ownership of the Panama Canal, and heavy Communist Chinese influence in the shipping terminals at either end of the canal (COSCO), It would take relatively little for communist interests to deal a nasty blow to heavy industry in the US, which has become reliant on imports.
Similarly, environmental regs have taken a toll on the petroleum industry, with new refinery construction severely limited. Refits to comply with EPA mandated reformulations of motor fuels have curtailed refinery capacity.
Even now, refineries are operating at an unprecedented 98% output; there are simply not enough of them. Regardless of imported crude amounts, refinery capacity remains a bottleneck.
The more we have to depend on imports, the more exposed we are, strategically, to terrorist antishipping attacks.
It isn't a question of sinking enough vessels to couse us harm, only a question of sinking enough to make it undesireable to haul cargo to the US.
It's like someone said before...whatever happened to the Monroe Doctrine? It seems to have gone out the window with the "collapse" of Communism.
