This whole concept is completely anti “achakeh lo becho yom sheyavo.”
ETA: I don’t necessarily mean the concept of ikvesa demeshicha, I mean more saying that moshiach can’t come yet because there hasn’t been a real ikvesa demeshicha yet or really stating the thread title’s question: “Is Moshiach’s arrival really imminent?” The ikrei emunah would imply that that’s self-evident.
