I certainly think that’s the long term trend. But …
For a cautionary note, consider Iran under the Shah followed by the Ayatollahs, Turkey under Ataturk, et al, up to now Erdogan, and Egypt under Sadat followed by Mubarak and now Sisi.
In each case a secularizing government along with a secularizing largely urban polity was initially succeeding in their efforts to relegate religion to a matter of minor personal conscience, not a default public morality enforced (at least around the edges) by secular law.
Then the backlash hit. Enough of the religiously conservative populace said “this is too much too fast.” Largely the more rural, less educated, and older folks at first. Who then attracted the attention of some fraction of disaffected youth highly susceptible to online
proselytizing rabble-rousing. Soon enough a suitable authoritarian champion in (semi-)clerical garb duly appeared to jump to the head of this mob and lead the country back into a theocratic Dark Age from which none has yet emerged.
To be sure there are significant differences between these 3 countries. Iran is nakedly avowedly theocratic; the authoritarianism comes second and flows naturally from the tenets of the official religion. Turkey is authoritarian with theocratic credentials; AK derives its legitimacy from its claims to be pious and always has. While Egypt is using a theocratic excuse as a (very) thin fig leaf for plain old military kleptocratic authoritarianism. Yet the thin fig leaf still sells in the ultra conservative quarters of society;
All three of these are of course Moslem countries, which the USA is not.
Poland is a similar example to Turkey but fully within in the Christian tradition. The rural hinterlands represent a hefty chunk of the voting power, are overwhelmingly Catholic, and have roundly approved the current batch of semi-authoritarians who’re using appeals to cultural/religious orthodoxy as a large part of their claim to governing legitimacy. Orban in Hungary is all the same with an especially nasty overlay of ethnic prejudice. Poland is too ethnically homogenous for that particular hate-mongering to get much traction. Not so Hungary. I don’t really need to explain how well ethnic hatred sells in the USA.
The USA almost certainly cannot reprise what happened in Iran. But something approximating Turkey, Poland, or Hungary is a distinct possibility. A Trump-like charismatic figure with ties to the military and slightly better faith-based credentials could certainly reprise General Sisi’s takeover in Egypt while being applauded wildly by both the US Evangelicals and the US cultural conservatives. Plus the America First! crowd. Throw in some white supremacy and it’ll sell like hotcakes.
