In 1977, Johnson's best-selling How Long Will South Africa Survive? offered a controversial and highly original analysis of the survival prospects of apartheid. Now, after more than two decades of the ANC in government, he believes the question must be posed again. 'The big question about ANC rule,' Johnson writes, 'is whether African nationalism would be able to cope with the challenges of running a modern industrial economy. Twenty years of ANC rule have shown conclusively that the party is hopelessly ill-equipped for this task. Indeed, everything suggests that South Africa under the ANC is fast slipping backward and that even the survival of South Africa as a unitary state cannot be taken for granted. The fundamental reason why the question of regime change has to be posed is that it is now clear that South Africa can either choose to have an ANC government or it can have a modern industrial economy. It cannot have both.'
