Sure. But let's go point-by-point. This is not to say that Republicans have not turned against their former beliefs and aren't in thrall to Trump, but some of these issues are more complicated than they seem.
As for the first boldface font, remember Ron Paul at CPAC? Straw polling as the leader in 2012 under the explicit platform of ending our involvement in both Afghanistan and Iraq? He won the straw poll by ten percentage points over Romney. The American Right has always had a strain of isolationism. In fact, it was only the Cold War that made Republicans interventionist, and that was the uneasy alliance of the Cold Warriors and the elite intellectual rightist establishment thinkers who saw that in order to remain democratic, we must engage the world and end communism in Soviet Russia and its satellites within the Eastern Bloc.
Republicans did not criticize veterans, indeed. Unless they were deemed not Republican enough, like John Kerry. Then they criticized plenty, starting with Vietnam and on through to the Swift Boat brigade in 2004. So it's not that easy.
As for the church issue, the overall churchgoing rate in America has plummeted. I'd imagine it has plummeted even further for Democrats. We're a more secular country these days. Whether that secularism amongst Republicans allows them to tolerate Trump I don't know, but I do know the first thing he reaches for when he's in trouble are churches, flags, and Bibles, same as any other politician, but maybe a little more egregiously.
Now, there are many things Trump has exacerbated. I'd say the most definitive yet most nebulous of these things are found in the musings and writings of the new American "intellectual" right. A love of government expansion into the economy and nationalization of projects and industries is one thing that Trump has overseen. Another thing Trump has overseen and added to has been a decrease in a fidelity towards the democratic process as an important one. Ends are more important than means with he and his followers. There are other things, but it is hard not to find a strain of thought anathema to conservatism and the American Right, because the American Right has been many things at many times. It has always been a confused and muddled movement, beset by as many pluralities as Democrats, and even more so than them. It's never written that way, but it certainly is so. It took a Cold War and a magazine (National Review) to cement its coalitions of very disparate groups into a cohesive working party, as it were, and it seems those coalitions have splinted or moved leftward, leaving the Party up for grabs ideologically.
The Right was united for a time. The menace of communism lurked, and everybody from religious folk to parts of labor to extreme libertarians were able to make common cause under the grand notion that an individual possessed freedom of conscience. That was the Right's crowning achievement. Now, it seems, freedom of individual conscience is not enough. The Right no longer sees that this is possible without crushing and deleterious effects to the soul, so it needs a platform, a new burst of energy. A new cohesion built on an abstract notion of purity of soul. It seeks a cohesive way of seeing the world now that the old coalitions are fragmented and destroyed. "Standing athwart history yelling stop" was good enough of a slogan for a time. That the New Right finds its energies so close to another form of history yelling "go" is troublesome.
