You are like these smokers who got cancer, trying to find other causes of their cancer.
The cause of downfall of Great USA will be...... bunch of fat russian hackers/trolls.
George Washington already predicted what the downfall of the USA would be... It would be "from the inside out". The treasonous insurrectionists both in government and in our population attempted, and failed, to bring down the US that way.
The uneducated, fat, communists that have to wait on line for 8 hours to be given their monthly ration of bread, with their rusted and useless war machines and worthless currency is not, in any shape or form, even a tiny little risk to the USA. They will go the fate of North Korea and disappear into irrelevance.
I think they're more likely to adopt the China model, and (continue to) insinuate themselves into the power structures of third world nation, even at the expense of relegating their own populace to living in similar conditions.
