on one hand far right goverment, eugenics, and totalitarian state cults would be considered relativelly normall, even as a good and practicall oposition to comunism, and even do there would certainly be camps and crimes on massive scales, there would be no direct campain to exterminate or dehumanise any given part of the population on national or ethnic bases, so that these would be seen as necesary measures against comunists/terrorists/criminals or whichever name is given to the ones getting killed
these crimes would not be so videly known as there would be the standard cowerups, but also as these would newer reach the level of atrocity of the nazy camps, so there would be little fuss about them in the western world, and might even be emulated to a degree
in a period of economic instability and rise of and civil rights and workers movements, the ways of fashism and fashist ideology would be borrowed by manny western regimes and become relativelly aceptable
without public condemnation, chauvinism, militarism and all the other ways of thinking and doing politics that make the 1920-1930is right wing what it was would find in fashism its legitimation, a confirmation that they are right and that they do work, and would have even more influence than OTL
with no radically racist regime influencing most fashist politics, statism rather than racism would become the norm, with lojalty to the nation flag the party and the state being more important than blood sciences and ethnic identity
on the other hand fashist regimes would become increasingly absurd
buffoonery is really the right word
lets not ewen start on the whole sublimation of sexual frustration and dominance of phalic simbolism
alhough the transferance of sex drive into technological advancment and bloody colonial expansion, as was activelly endorsed by futurism, could of given some trully interesting results
the state controled economy would give security and stability for a while but soon the obvious problems of state controled economy that emfasises on military industry would start to show, and major economic recesion would be dificult to stop, althou there would probbably not be any real economic depression, especially with exploatation of colonies, and cheap east european labour, unless colonial expansion is halted by a european war, in wich case they are screwed
no real worker movement would result in low pay and poor working conditions, general economic conditions, wages and quality of products and service would deteriorate
after a couple decades the economy would lag far behind those of capitalist states, or even soviet economy
without constant conflict and war, the sistem most likely stagnates, economically, politically, and tehnologically, and becomes basically a large banana republic
therefore there would be the constant manuvering on the brink of war, stepping ower into limited conflicts and interventions, but alvais trying to awoid escalation, as ewen a marginal defeat in a major war would be enough to throw down a fashist regime
as such fashism would eventually become something seen as a last measure, something to be avoided, and ended as soon as possible, even if manny usefull tips and customs would be incorporated in how things are done in "democracies"
even with the soviet treath most fashist regimes would end as soon as the Soviet Union colapses, and would probbably go in a way similar to the romanian dictatorship, or a longer civil war
thats granted the soviets colapse if theres no WW2, if not the oposite might happen, fashist nations colapse, and become right-wing regimes
the olnly things that can save long term fashism is Germany turning fashist, with a strong centralised militarist dictatorship, but no nazy crazines
that would give european fashism the economic, and tehnologicall power it would othervise lack, as well as a good dose of germanic mentality
and/or the development of a economic model similar to OTL China in the last few decades, using relativelly cheap locall labour, concentrated in what is still labour intensive economy, to produce export goods, and atract forein investment
still a mayor question is how would a potentiall alternative WW2 go with a fashist party in power in Germany, meaning mostly military and demochristian figures in power, and possibly much more competent military comand that has a way of acepting actuall reality
given that a fashist Germany still makes part of the Axis and starts the second war in Europe, this might end after the capture of France and Scandinavia, with the partitioning of Balkans and east Europe, and important gains in Africa
ewen in a war with the soviet union, germany without nazis has a much bigger chance of marginall wictory or at least breaking even, but with no hitler the Third Reich and the Soviet Union are naturall economic allies and there might not be any war with Russia
if all these things happen fashism might do somewhat better economically, or after some administartie reforms make for a more efficient economy, and the cheap resources from colonial gains, there would be a period of prosperity and general growth
also fashism and comunism, or their derivates, could become the two dominant world ideologies
but none of this is possible without a fashist Germany, wich as already said is not a nazy germany, and definitley without people like Hitler and Goring making important decisions
