Michael, that FT piece about the network of doctor-terrorists is very interesting. This BBC story says of the two docs arrested this weekend:

Dr Asha was described by family and university colleagues in Jordan as a “brilliant” physician who had not been involved with extremist organisations. According to his father Jamil, he obtained a medical degree in Jordan in 2004 and came to the UK in the same year to gain a specialisation in neurology. Dr Abdulla is said to have qualified in Baghdad in 2004 and first registered as a doctor in the UK in 2006.

In other words, although both doctors trained in their home countries, neither of them practised there. As soon as they qualified, they left for the west, whose government health services have a chronic shortage of medical personnel that can only be filled by fast-track immigration from almost anywhere on the planet. If that’s a strategic decision to exploit a vulnerable express check-in to the western world (as they did with Britain’s fast-track imam immigration program of the Nineties), it’s an extremely canny one.
