E.M. Cadwaladr "The thought of Civil War has been in the minds of many people lately, on both sides of the political and cultural divide. This is not a thing to be wished for, though no one should kid themselves into believing it’s impossible either. Let us take a sober look at what such a conflict might entail."
. . .
"Given an absence of legitimate government and the friction of proximity, ordinary people can be moved to settle grievances by killing one another without the need for governments to egg them on.
"Some dimensions of a future civil war would be, I think, largely unprecedented. When lesser countries have imploded in violence in recent times, they have done so with most of the world around them still intact. There were other nations to offer aid, assistance and intervention, welcome or unwelcome. There were places for refugees to go. The collapse of the world’s remaining superpower would take much of the world down with it. A global economic crisis would be inevitable. The withdrawal of American forces from bases across the world to fight at home would also create a power vacuum that others, even under economic strain, would be tempted to exploit. Whichever side gained control of our nuclear arsenal, our status as a nuclear power would probably persuade other nations not to interfere in our conflict militarily, but the collapse of trade alone would produce crippling effects that would be hard to overestimate. Many components for products our manufacturing sector makes are globally sourced. Add to this the breakdown of our transportation system, dependent on oil and transecting one new front line after another. The internet would fail. It is a frail enough now. Financial systems would fail. What happens if the banks find half their assets suddenly in hostile territory?" . . .
