This was as good read and articulates many of the "what about this" sort of questions I've been having around the news. This clip (https://youtu.be/smemFVe0l5E?t=5418) of Tucker Carlson interviewing Senator Ted Cruz from nine-months ago popped in my head reading this. Invading Iran has been some US conservative dream for decades and now that all the people who have been telling them it's a bad idea are gone they're pushing ahead, consequences, history, and the rest of the world be damned.

I think you're reading too much into that. Evangelical Dispensationalism is what is the driving force behind the particular brand of Neo-conservatism that Ted Cruz espouses.
