I agree that Italy still is mostly Italian, though even with the absence of decent welfare, the very geographic vicinity and climatic affinity will still let many stay. The numbers of Muslims is 1,5 mio., will be easily 5 mio. by the end of the decade and 10-20 mio. depending on immigration by 2040-2050.
Also - the EU is discussing an EU-wide welfare model that will then hit the lower-cost countries in Eastern and Southern Europe harder. Give it a few years...
Discussions about that most European countries comprised of different tribes in ancient tribal systems are moot. So what if Germany consisted of some 100 countries a few centuries ago? European nations have formed themselves and many are quite similar - also shaped by Christianity - some populations could be ethnically exchanged and you would not see much difference if you did so. If someone cannot understand the reality of ethnic replacement, differences in religion - even basic raw evolved intelligence and ethnic similarity of some European tribes, then any discussions are moot, because you are essentially spouting the Soros-dogma of everyone go mix - but we Ashkenazis will only breed with the highly intelligent European goys and now maybe Chinese for our continued supremacy.
Not much - covidianism will clobber Europeans harder than mass migration would in a few decades. Population replacement could of course be stopped, but you would need to replace the entire leadership and the stem somehow the global leadership. And as far as that is concerned - mainly Iran and Syria exist as independants. I discount the other few African countries, because they have no significance to the global elite.
Will this displacement agenda succeed?
Yes - unless a miracle happens and the ruling globalist elite lose control and real right-wing leaders come into power. I don't think that it will happen, but you can always hope. If someone believes in that victory like Sweden's Golden One, then I respect that. I just don't share his view.
How did we let this happen?
'We' had not much to do with it. It was by design over decades - a well-planned attack against all European and Christian peoples. In the US it was the elimination of the European Christian based immigration laws that were promised to not change the ethnic makeup of the country. In Europe they did it by constant brainwashing in school and media until the full floodgates to be opened. Even the importation of the Turks in the 1970s was according to some accounts done due to pressure of the US which played even then the lapdog of the global elite. Sometimes it came in waves like the windrush in the UK with a break afterwards. Then it opened fully starting in the 1990s for ths kill-shot. Most people still think that they will have their own country even if it's more 'diverse'. And when some uber-British men like John Cleese complain that London is no longer British and the culture is disappearing, well then he must be a racist.
It is not us who did it - it's just that most people were too removed from the movements of power to realize what is happening, or how brainwashed they got.
Heck - even if a real right-winger got endowed with the powers of Superman and enacted all the plans with the barely any violence and mostly with financial incentives (deportation by paying out immigrant citizens) - a sizeable part of the European population would fight him being so brainwashed. That Superman would have to seize a good portion of the mainstream media and academia, completely revamp what has been done to them for 70-80 years - a process which easily started in boomer time of the 1950s with James Dean movies and that pushed marriage of that Mexican girl. (and I personally don't mind that very fact of mild or more diverse race-mixing - just that it gets pushed to the front in such an important big-budget movie as a propaganda tool for far worse things to come).
There was a saying in the 1950s USA - the working class were Democrats back then, the middle class were Republicans and the upper class were all Communists. Now the middle class are Democrats, the new non-Euro immigrants are Democrats - and many of them including the elite are all communists. The Republicans are now a mix of Zionists, cuckservatives and only partly working class if a guy like Trump is not in power.
John Cleese was right - his hatred for the commies was justified - just that communism is a Jewish and elite created monster:
This ship will continue down the same path so long as the filthy commie bastards are not dead - or better put - the ones who financed communism - the billionaires and trillionaires of our world.
