How can we implement Nation Socialism in western countries? Is it even possible?

All forms of left wing economics are functionally impossible without ethnic nationalism. There is no world in which you have a multi-cultural society that works with left wing economics. There is no world in which ideological and class unity is strong enough to overcome the latent flaws in a left wing economic system. Literally the only way left wing economics works is via ethnic homogeneity. The farther left your economic policies are the farther right your social policies must be to counteract doctrinal flaws.

The more we (whites) interact with non-whites, the more we become racially loyal.

That is not a national soialist soldier on the picture tho, he is WWI.

maybe, still you americans put individualism first, so good luck convince people to put white race first.

>LARPers who were the first civilization to enter space, built the first electric computer, and produced arguably the finest philosophical mind of the 20th century, Martin Heidegger, in addition to building a military so strong that it took 4 globe spanning empires 5 years to barely beat a country 1/3rd the size of Texas

pretty good as far as LARPs go
