"What we need now is a way to exterminate the vermin..."
That's true. That's always been true.
But we must avoid the trap of thinking that the 'vermin' can ever be totally eliminated, because they can't. We can, and must, win the struggles that we're faced with, but we mustn't ever imagine that these struggles themselves can be eliminated.
Vermin can be managed, hounded, forced to pay a price, compelled to evolve into new kinds of vermin or eliminated. (at which point they'll promptly be replaced by other vermin)
If we go into these struggles with a realistic understanding that they are multiple, ultimately serial, events which are always going to be chronic maintenance situations, rather than a single predicament with an eternally victorious conclusion, we'll be better prepared to do what we must (always) do.
