Its interesting to consider the possibity that the road to global communism might involve "back-tracking" to a more nationalist mode of production away from global/international capitalism. Then agian, Lenin did say that internationalism was the final stage of capitalism so perhaps communism on global level could be achieved without the need to re-visit the odious nationalist phase.
Comrade, it is impossible for capital to isolate. This is what the Great Depression was, Germany isolated its economy and everyone did the same to not get undercut and this is what made the 30's such a huge crisis. Now people learned and have not regulated capital, and it sort of worked, of course capitalism is though at its end once more. This is not to say they can't reform it, but we have a lot of work to do because people want to see alternatives. This said, if countries start to choose to subsidise local farming and local production, capital would have huge problems because it always needs to expand areas of production/consumption to get investment and survive. By the way, last week i ate lamb and it was from Australia! WTF, i am in Germany and there needed to be about double the calories in the actual product itself used to get it to my plate. This system is unsustainable, communist world revolution FTW!
"It is necessary for Communists to enter into contradiction with the consciousness of the masses. . . The problem with these Transitional programs and transitional demands, which don't enter into any contradiction with the consciousness of the masses, or try to trick the masses into entering into the class struggle, create soviets - [is that] it winds up as common-or-garden reformism or economism." - Mike Macnair, on the necessity of the Minimum and Maximum communist party Program.
