Having plans in place is not a problem
Running around like a headless chicken when the proverbial shit hits the fan is. So yes, it makes sense to have plans in case war breaks out.
Thus, I do not find it at all surprising that there are plans in place for both defensive and offensive action. What is a problem is their constant data gathering on everything. Adding more data to a pool indiscriminately is like wall-of-death fishing: you catch and kill all sorts of stuff you did not intend to. I also do not buy the argument that they have "advanced data-mining algorithms". Data mining is a fancy word for pattern recognition in big data. To stay in the parlance of mining, let data be the ore, and information be the metal you want to extract. As the percentage of metal in the ore becomes lower, it makes less and less sense to extract the ore from the ground in the first place, unless the metal is very very precious. Even then, it is possible to be sidetracked by things that look like the metal, but aren't. Fool's gold (iron pyrite) springs to mind.
Likewise, if you gather data about everybody, looking for a minute percentage of people that actually hate the US sufficiently to do it real harm, the chances are false positive rates will skyrocket. This is a very real danger. It is much better to gather information in a far more directed manner, instead of implicitly suspecting everybody of ill will (which in itself seems to be a self-fulfilling mode of action).
As I have said over and over again: adding hay does not make finding needles easier. In mining parlance, there may be gold in them there hills, but it is better to drive a well-chosen shaft than indiscriminately removing the whole range of hills from the face of the earth, and sifting through tons of worthless rubble.
Given that the earlier leaks were about the far more dangerous data snooping, a cynic (who? me?!), might think this leak is there to distract from the more dangerous issues.
