A great advantage of that intentionally destructive, spiteful, "Sorathic" evil which characterizes the current Western national leadership class; is its covert nature.
Because everybody is always trying to make sense of what are merely destructive impulse; and in doing so, people come up with multiple and incompatible theories concerning what positive goals They are trying to achieve.
And - ultimately - all these theories are wrong!
For instance; more Western people have (eventually) begun to notice that their rulers are puppets operated by multinational and foreign agents; and have noticed that these rulers are allowing and abetting the invasion of their nations by colossal numbers of foreigners.
Having noticed what is going-on; people try to understand it in terms of what benefits (whether short-, medium, or long-term) are expected to accrue to a variety of persons and groups as a consequence of massive influxes of "aliens".
This results in many and competing theories - each theory claiming that somebody different is behind the invasion; and each of these rival malicious actors is striving to get something from a range of benefits such as wealth, power, status, sex etc.
Public opinion then fractures into rival theorists, with rival plans of how to combat the putative groups and prevent them getting... whatever it is that They intend to gain from the mass invasion of the West.
However; if it is true that what is being aimed-at by those who are ultimately responsible for the invasion of the West at is simply the destruction of the West (its civilization, institutions, people etc.); and that the primary motivation is not gain but instead the spiteful gratification of those responsible -- then all these theories are irrelevant; even when a theory may be partially correct for some people, at some level.
Meanwhile; the work of destruction proceeds unimpeded, invisible, undetected.
