"This article argues that during the early twenty-first century,
generally we have witnessed greater intelligence co-operation in
Europe. Indeed, we can even appropriately discuss the increased
'regionalisation of intelligence'. Effectively reflecting 'uneven and
combined development', persistently these co-operative intelligence
trends appear to be occurring haphazardly, non-uniformly and at
several different rates at the different levels of relations in the various
'pockets' of European intelligence co-operation. This article concludes
by arguing that overall there is the development of an ever-more
complex web consisting of a plethora of various overlapping
international intelligence liaison arrangements that collectively
provide a form of regional intelligence coverage in Europe. How they
overlap is important, accounting for the connections, and notably the
'disconnects', that publicly come to our attention." -- abstract from journal (see link).
