Back in the Op Banner days there was a little known Contingency Plan developed over a two year period of what to do in the event that all out civil war began in NI. It had a Military Contingency, it had a Civil Contingency, it had a Contingency for Air Transport and for Ports, it had in fact, a Contingency Plan for almost every aspect of socio-economic life including a Civil Service proposal for administrative government of the province. It had a plan for population relocation (what we would now call 'ethnic cleansing' - but, it was a plan. The whole thing was produced, refined and reproduced until it resembled a workable proposition and, thankfully, it was never needed.
You would think that the tossers at Westminster some fifty f**king years later would be capable, with all the technology and 'expert' business and legal minds at their disposal, of coming up with a programme of debate, issues to address and a mechanism through which to conduct some kind of workable review into this bloody shambles - because any plan thus produced is definitely going to be used.
