Israel (and jews in general) are absolutely screwed. This is because the U.S. is screwed. Everything that we (the people in power and all the useful idiots going along with it) could be doing to collapse our nation (and entire civilization), we're doing, with gusto. Money printing, endless inflation, a shit job market, devaluation of the currency to uselessness, mass importation of foreign workers, outsourcing, making it nearly impossible to eat or pay the bills for the average man, demonizing all rationality and the most mundane of positions, censoring men and pushing them into the far right, giving no effective outlets for men (clubs, hobbies, stories, heroes, privileges), corrupting all political parties and leaders, leaving no effective political alternative, blatant corruption and cheating in politics, pushing citizenry toward only one possible solution, endless foreign wars and conflicts, the blatant hypocrisy and anti-White hatred in all modern media, intentionally importing people who can't maintain our systems, antagonism of the native (White) people such that support for the corrupt systems steadily decreases, neutering of the military enforcement of globohomo, media and governments lying so blatantly that even the normiest of normies are noticing, giving people so little option in how to fix our problems that open discussion of the most verboten topics is now occurring and accelerating, the push of LGBTQ and pedophilia, putting more and more burden (taxes, police, enforcement, upholding civilization) on the backs of fewer and fewer men/producers, importing and creating more and more parasites/takers, pushing men away from upholding civilization via apathy and hedonism (drugs, porn, video games, etc.) or out of society in total (homesteading, farming, leaving for other nations), etc.....

Once the American empire collapses, all of globohomo collapses, including the lion's share of the military industrial complex, the propaganda machine, the fiat dollar, central banking, OPEC, the poisonous medical industry, the "food" industry, globalism in general,...everything collapses. The U.S. military is the primary enforcer of globalism and protector of Israel. Once America (and the West) collapses, Israel is 100% fucked. Once the propaganda machine collapses, jews everywhere are 100% fucked, because everyone is going to look to who caused this shitstorm, the propaganda will be gone, and the people who keep being proven right (the race realists and jew aware people) are going to gain an increasing audience and following.

The only way they survive is somehow clawing back the US millennials and younger generations. How would they do that?

They're going to try to push the Kalergi plan as hard as possible, but it's going to backfire the more they do this. Non-whites can't be race shamed like White people because the foundational myth of globohomo is WW2 and the Holocaust. Jews may try to push the "God's chosen people" propaganda via Christian corruption, especially among the Christian central and south Americans, but I don't think it'll work well. Too many young people are waking up to the truth. Granted, non-whites vote left wing in majority, giving them a better voting base, but voting hasn't mattered for a while now, and nons can't maintain Western civilization, leading to incompetency crises everywhere they take over, which will cause the American empire and Western civilization to crash even faster.

The only thing they can do at this point is to slow roll the collapse as much as possible. They can only slow it down, not stop it. I think a lot of them know what's coming, which is why so many of them are building underground bunkers, hoping to ride out the shitstorm they're creating. They may try to flee to competing foreign nations, like Russia and China, in the hopes of subverting them as much as the U.S., to turn them into a new golem enforcer, but I don't think that'll be effective either. Once the collapse hits, once the American empire and Western civilization collapses, it will affect the entire planet, on a massive scale.

What most black pillers assume is that this civilizational collapse will lead to the complete annihilation of White people. They're wrong. Collapse is necessary to root out the systemic corruption and evil in our nations that we can't fix any other way. In addition to completely neutering the monopoly on information sharing (except for the internet) and the propaganda machine, the collapse will cause mass ethnic violence and ethnic collectivism (even among the propagandized White population). This will push a lot (perhaps most) of the parasitic non-white freeloaders back to their countries of origin, reinforcing the White collectivism happening at the same time. It'll take years to reestablish White nations free from the corruption, but once that takes place, those White nations will be out for blood, and even more violence and wars will take place. Some might speculate we will become insular and peaceful after the collapse and initial conflicts, but the only leaders who will attract any support will be incredibly strong, and have zero remorse toward our enemies. Weak leaders will be completely abandoned, or lead to the deaths of all who follow them.
