Give examples, say from the Spanish Civil War, or other examples of workers autonomous zones? I am particularly interested at this point in what you mean by "appropriate reaction to threats"?
Try wikipedia:
Along with the fight against fascism was a profound anarchist revolution throughout Spain.
Much of Spain's economy was put under worker control; in anarchist strongholds like Catalonia, the figure was as high as 75%, but lower in areas with heavy socialist influence. Factories were run through worker committees, agrarian areas became collectivized and run as libertarian communes. Even places like hotels, barber shops, and restaurants were collectivized and managed by their workers. George Orwell describes a scene in Aragon during this time period, in his book, Homage to Catalonia:
I had dropped more or less by chance into the only community of any size in Western Europe where political consciousness and disbelief in capitalism were more normal than their opposites. Up here in Aragon one was among tens of thousands of people, mainly though not entirely of working-class origin, all living at the same level and mingling on terms of equality. In theory it was perfect equality, and even in practice it was not far from it. There is a sense in which it would be true to say that one was experiencing a foretaste of Socialism, by which I mean that the prevailing mental atmosphere was that of Socialism. Many of the normal motives of civilized life--snobbishness, money-grubbing, fear of the boss, etc.--had simply ceased to exist. The ordinary class-division of society had disappeared to an extent that is almost unthinkable in the money-tainted air of England; there was no one there except the peasants and ourselves, and no one owned anyone else as his master.
The anarchist held areas were run according to the basic principle of "From each according to his ability, to each according to his need." In some places, money was entirely eliminated, to be replaced with vouchers. Under this system, goods were often up to a quarter of their previous cost.
Despite the critics clamoring for maximum efficiency, anarchic communes often produced more than before the collectivization. The newly liberated zones worked on entirely libertarian principles; decisions were made through councils of ordinary citizens without any sort of bureaucracy. (The CNT-FAI leadership was at this time not nearly as radical as the rank and file members responsible for these sweeping changes.)
In addition to the economic revolution, there was a spirit of cultural revolution. Oppressive traditions were done away with. For instance, women were allowed to have abortions, and the idea of "free love" became popular. In many ways, this spirit of cultural liberation was similar to that of the "New Left" movements of the 1960s.
Or this, (re Ukraine):
At this point, the emphasis on military campaigns that Makhno had adopted in the previous year shifted to political concerns. The first Congress of the Confederation of Anarchists Groups, under the name of Nabat ("the Bell"), issued five main principles: rejection of all political parties, rejection of all forms of dictatorships (including the dictatorship of the proletariat, viewed by Makhnovists and many anarchists of the day as a term synonymous with the dictatorship of the Bolshevik communist party), negation of any concept of a central state, rejection of a so-called "transitional period" necessitating a temporary dictatorship of the proletariat, and self-management of all workers through free local workers' councils (soviets). While the Bolsheviks argued that their concept of dictatorship of the proletariat meant precisely "rule by workers' councils," the Makhnovist platform opposed the "temporary" Bolshevik measure of "party dictatorship." The Nabat was by no means a puppet of Mahkno and his supporters, from time to time criticizing the Black Army and its conduct in the war.
In 1918, after recruiting large numbers of Ukrainian peasants, as well as numbers of Jews, anarchists, naletchki, and recruits arriving from other countries, Makhno formed the Revolutionary Insurrectionary Army of Ukraine, otherwise known as the Anarchist Black Army. At its formation, the Black Army consisted of about 15,000 armed troops, including infantry and cavalry (both regular and irregular) brigades; artillery detachments were incorporated into each regiment. From November 1918 to June 1919, using the Black Army to secure its hold on power, the Makhnovists attempted to create an anarchist society in Ukraine, administered at the local level by autonomous peasants' and workers' councils.
The agricultural part of these villages was composed of peasants, someone understood at the same time peasants and workers. They were founded first of all on equality and solidarity of his members. All, men and women, worked together with a perfect conscience that they should work on fields or that they should be used in housework... Working program was established in meetings where all participated. They knew then exactly what they had to make.
—Makhno, Russian Revolution in Ukraine
New relationships and values were generated by this new social paradigm, which led Makhnovists to formalize the policy of free communities as the highest form of social justice. Education was organized on Francisco Ferrer's principles, and the economy was based upon free exchange between rural and urban communities, from crop and cattle to manufactured products, according to the science proposed by Peter Kropotkin.[citation needed]
Makhno called the Bolsheviks dictators and opposed the "Cheka [secret police]... and similar compulsory authoritative and disciplinary institutions" and called for "[f]reedom of speech, press, assembly, unions and the like".[13] The Bolsheviks accused the Makhnovists of imposing a formal government over the area they controlled, and also said that Makhnovists used forced conscription, committed summary executions, and had two military and counter-intelligence forces: the Razvedka and the Kommissiya Protivmakhnovskikh Del (patterned after the Cheka and the GRU).[14] However, later historians have dismissed these claims as fraudulent propaganda.[15]
The Bolsheviks claimed that it would be impossible for a small, agricultural society to organize into an anarchist society so quickly. However, Eastern Ukraine had a large amount of coal mines, and was one of the most industrialised parts of the Russian Empire.
And can you guess what they both had in common?
Though, in any event, anarchism isn't bound to repeat the experiences of the past. As people have repeatedly told you, the way anarchists respond to any situation will depend upon the prevailing conditions.
