It is, just check out wiki on some of the main symbols of Revelation. I remember Hank Hanagraff finally disclosing himself as historicist. There is strong evidence in Revelation of some sort of historicist view. I am unpersuaded myself, as there is a difference between *conclusive* evidence and strong evidence.
Also, as I noted, Catholicism, is, of course, very big and while I disagree with a lot of their viewpoints, they do have a number of the historicist viewpoints... and with some good reason.
But, I tend to view, instead, the events of the past as likely related to something happening in the future.
I think, besides, for instance the major failings of Christian majority states: the inquisition, colonialism, neo-colonialism, the mess the US has been making in Muslim lands, and so on... this, though, remains a problem for me.
My view is more that these nations want to seduce Christians with the idea that they are with them, but their actions seem to show they are against them.
I have to say God surely was behind some of these behaviors, however, even if they were savage. God is known to work with where people are and with even their savage tendencies. Otherwise, how would we as human beings have any converse with God at all?
I am not at all so sure about fulfillment of the last seven plagues being as you say. Cancer has been around but only recently identified as such, for instance. You see really horrendous plagues in the Middle Ages. And then in the last century you saw really incredible evil in Hitler and Stalin, as well as across the world (Hoover, Pol Pot, Mao, and so on).
