It should be glaringly obvious that if, as so often touted in the MSM, there are 'Markers' of Chinese, British, Israeli, Russian, or Eastern European meddling, then (1) the intelligence agencies of those powers, and many freelancers, know that too, (2) it will be possible to mimic them and either hopelessly confuse the trail or pin it on someone else entirely, and (3) there are probably markers of US meddling of which we are blissfully unaware. Of course nobody in the MSM is enough of an actual thinker to bring this up until something like Wikileaks actually rubs their noses in it and spanks them.
