Following on from the book, This theory is based in part on those premises.

Some brief notes before I expand on these premises

The conclusion was the United States would collapse down to third world conditions due in large part to the negative relationship between smartness and number of children.

Western Europe and Northern Europe from Spain through to Finland will in my estimation become a part of Islamic Civilisation but why do I think this.

Well I think that the levels of religiosity of these Islamic countries are a reflection of there respective collective natures rooted in genes and I think culture is to a large extent internationally a reflection of a peoples collective nature at a period in time.

In addition the conservatism fertility correlation is positive among muslim which means if there are any genetic contributions to this trait those traits are under Darwinian selection to increase.

In addition both political parties in the UK being thoroughly committed to immigration and pretending they are not along with the first past the post voting system makes this trend impossible to arrest and thats assuming it can still be reversed on current birth demographics in the UK.

Anyway the intermarriage rate among North American Ashkenazi Jews that are essentially Southern European is 60% on most recent estimate said Ashkenazi make up 80% of international Jewry.

The theory I am exploring now that is its infancy is that due to the state of israel maintaining civilizational health on values of faith, flag, family, whether civilization will pass there as ours decline into our most recent dark age for the next several centuries.

My big picture prediction of which I am 70-80% confident at time of writing is that by having sharp minds per capita the Israelis are resistant to falling cleverness for quite a while, the intermarriage rate and the percentage of the globe that is Ashkenazi as well as these values giving them strength as a civilisation would turn the state of Israel into a European Colonial Power

Addition

Historically Arab conflicts have lead to Israeli annexation; this should lead to more Israeli annexation in the future, although they are currently undergoing expansion from west-bank settlement.

Assuming a fall in IQ within Israel will be moderated in rate by political orientation and that's impact on association between IQ and fertility which should help to stave off the problems found in Low IQ nations such as violent crime, dilapidated living conditions and malnourishment.

The current Israeli immigration system is very liberal and open to anyone who is 25% Jewish or more, converted to Judaism or married to a Jew.

intermarriage with Northern Europeans will make the Ashkenazi close.to the romans genetically, they already making up a large majority of world Jewry,

when the United States collapses or the Israeli economy overtakes the US per capita,

the American Jews will move to Israel with the possible exception of the Haredi Jews on religious reasons and less likely the liberal Jews on Political reasons.

there is breeding for orthodoxy among American and israeli Jews and some evidence of a positive relationship among this group between iq and fertility,

the high iq advantage, influx of even more europeanised Jews after the collapse of the US and Arab conflicts and Israeli nationalism leading to annexation will create a short lived European heritage empire in the Middle East of blood similar to that of the romans.

Even the Israeli left aren’t for open borders so at most a political influx would arrest there expansion perhaps temporarily.

The high iq of Israel and its legacy of victory against Arabs in the Israeli Arab war plus its advanced military industrial complex make it highly competitive militarily with the US only supplying 15% of its military budget and this in a rapidly growing economy.

Israel’s nuclear arsenal gives it the ultimate deterrent and weapon of colonialism if they were to choose to use it.

The Ultraorthodox will have to have there funding cut as they grow to large and will make up due to there religion the lower social strate whereas the modern orthodox will makeup higher classes.

Some may argue that when China annexes Taiwan this will spell economic disaster for the west however Israel has one of the worlds most advanced silicon chip industries and if necessary could block exports which would be promising to meet local demand.

The Iran situation is tricky. Despite hints of regime change on the horizon they are close to developing a small collection of low yield nuclear weapons that would wound the state Jerusalem the capital would not be nuked though and the country would live on because of that and remain stable it would wound the state but attract much international sympathy from Jews and gentiles alike, it’s also possible they won’t use them as that would basically ensure there nuclear obliteration by Israel but the Iranian leadership is very religious they might be brave enough to do it, on the contrary they could use them on there own people if there’s a coup of discontentment.

The population density of the state will necessitate that annexation of future territory whether this will be an Israeli born development or a product of external war or terrorism.

The surrounding Arab nations should also be in dysgenics for IQ and there dependence on food imports makes them vulnerable in a collapse, the Israeli agricultural output has increased by 2.2% per annum which should make for 80% of food produced domestically by 2035, providing food security.

From a biosocial perspective the introduction of Ashkenazi in greater numbers and more Europeanised Ashkenazi at that is likely to have a biologically upward exerted pressure into Judaism causing a new branches and a broader evolution of the Judaism practiced in the country for a case study in the Judaism practiced we can reference Christianity and if we assume that the Jews that intermarry with White Gentiles are marrying Gentiles that are K strategists then we might assume that in some ways Judaism in Israel will come to more resemble Christianity overtime.

the change in genetic frequency of Israel towards a more European type will likely by genetic similarity promote more war in the region that would lead to more annexation by Israel.

The Map I have previously presented for the greater Israel is based upon the broadest religious definitions of Israel and therefore the most ambitious view of expansion and annexation that is likely to be realized, I would be inclined by virtue of there technological superiority to view these exact boundaries as being gradually manifested in the future.

It’s hard to know whether this introduction of Europeanised Jews will overall increase the genetic similarity by shifting the ratio of Ashkenazi to Mizrahi firmly in favour of the Ashkenazi or whether the new Northern European blood will cause greater division leading to more internal squabbling in the long term.

It’s possible the eugenic impact of Israel from IQ and Conservativism resulting in a Conservative government in the empire could arrest or reverse dysgenic decline keeping the empire going for a few hundred years longer than the pessimistic predictions and this would interact with the level of genetic diversity in the empire as another factor in its long term survival.

I think an Israeli Conservative Effectively Eugenic program is not beyond the realms of possibility as much as it would be in Most of Europe, US and the Anglosphere. I would argue a Eugenics program in essence is a combination of intelligence and binding values, conservative values possibly plus cultural context with respect to impressions of eugenics.

I found using a spreadsheet program an approximate political breakdown of Israel assuming a migration today of 50% leftwing 10% Centrist and 40% right-wing, this would cause a sharp rise in IQ but a faster decline than would be the case if it were more right wing.

The move towards sustainable energy sources such as renewables or nuclear, thorium being particularly interesting may help with industrial sustainability post-global-industrialism. Although its worth whats currently Iraq has good oil resources, useful in energy but also in plastic and hydrogen carbon product production.

The reason I predict the Israelis taking the whole of fertile crescent at the below defined borders is based on the broadest possible theological definition within Judaism of Jewish State which I think they will have the means to achieve I would predict them manifesting these exact borders but not wanting to go any further keeping true to the ideology of the Zionist mission.
