The news is replete today with PM Teresa May's well phrased outrage over the same US government leaks to the press that have outraged President Trump. In this case it is likely IMO that some group like NYPD under Mayor Blasio's influence leaked to the NY Times.
Let us be clear about the possibility that UK intelligence (MI-5, MI-6 and the military) or police intelligence will stop cooperating with the US IC. The possibility is ZERO. I know as much as anyone of the nature of the relationships of the US IC and its allies as anyone. The US contribution to all of these is somewhere between 80% and 95%. These folks have very little real collection and analytic capabilities. We give them everything and they cannot give us much of anything because they have nothing. There are exceptions. The US IC and the British "old boys club" are welded at the hip. Our thing grew from their thing in WW2. Before that our war plans were based on the idea of the British Empire as the enemy. The US IC and that of the UK are virtually the same thing in the SIGINT field and James Bond fantasies aside, no one has trusted MI-6 since Philby. Israel/US intelligence relations are overwhelmingly conducted on the basis of the Israeli attitude of "what's mine is mine and what's yours is mine as well." The French have excellent HUMINT in their former empire but aside from their excellent soldierly qualities the rest is not much. All the rest of US intel liaison relationships across the world is mostly a matter of diplomacy.
I am so tired of the mendacious BS. pl
