They're great for their societies.
While I don't like their methods I certainly can't fault them for wanting to secure the existence of their people and a future for their children. Are they bad for other societies? They certainly can be both at the elite level and on the level of the average schlomo, but again this is true for all races to varying degrees. Races have never and should never put other races above their own, so such behavior is to be expected. What is different about Jews is how they go about securing their existence. They use money and cultural subversion to "peacefully" genocide people that might threaten them. Domesticating them instead of decimating them, corrupting them instead of castrating them, replacing them instead of exterminating them. They got really good at these things because for thousands of years they either weren't capable or weren't allowed to do much of anything else and that "artificial selection" of the jewiest of the jew has only exacerbated their "negative" cultural/genetic behaviors and most importantly, their paranoia of other races.
If it's true that collectively, because of the Rothschilds, they have more than half of the total money on the planet and it's true that money equals power, then any race they deem a threat is pretty much fucked. The world has been cooled and solidified largely by their influence on cultures and politics under the guise of "spreading peace and democracy". Conquest and seizing of assets and territory is something nations or groups cannot effectively do anymore and they already have more money than any other group, so what can you really do to fight it? They can buy anyone who can be bought and they can kill anyone who doesn't have a price. Elections are cheap, influence and blackmail are as easy as inviting someone to a weekend getaway at a private island. Small nations can be kept in check by the bigger ones so long as you hold the political reigns of those nations. If you own enough media companies it doesn't matter if the others contradict the narratives you put out. With enough money you can erase people, history, ideas, anything.
The crafting of such a subtle knife really does speak to their high average IQ, but as I said I find such methods utterly contemptible. I wish they would just fight us properly and go about it like good sports. Crushing their enemies, seeing them driven before them, hearing the lamentations of their women, that sort of thing. But that's my European genes and culture talking.
Morally speaking, which is the "right" way to win? The races of Men are what they are, wild animals with the will to survive and (so far) the ability, against all forms of competition. Unless one accepts that, anything one says about morals, war, politics—you name it—is nonsense. The universe will let us know, later, which one was "right".
