It's not even division, I once heard it described as "planned destruction of concensus reality". It's what the idiots panicking over "Russian bots" and "Putin's playbook" fundamentally fail to grasp: getting people who hate Russia to go on a never ending hunt for Russian bots is much easier than getting them to like Russia, but equally makes them counterproductive to local politics.

Like that story from a few weeks ago, an AIPAC media campaign against an anti-Israel politician is less effective than AIPAC donating to him and then leaking it. Or, ideally, both.
