ORAC, the piece that you link to perfectly illustrates the dichotomy that exists between the EU concept of defence and that of the NATO/UK one of European Defence. The former is mumbo jumbo that would not survive first contact. I wouldn't want to fight and die for the EU, and suspect that goes for many in the armed forces of European States. In contrast the armed forces of the UK and USA have fought repeatedly for European freedom, and sadly not for the last time I fear.
The EU carries the seeds of its own destruction. If it continues pushing for ever closer unity then "unforeseen consequences" will follow as sure as night follows day. The UK will be well out of it, as will others who choose to follow our example.
