This is what is certain.
Antichrist comes first chronologically. When we see him and his armies surrounding Israel prior to his marching into the temple to the seat and declare that he is himself God THEN you may say that the Lord's return is imminent.
... they have not yet started on the temple, before they start on the temple they will have to clear the Arabs out of there [Jerusalem] so what we should be looking for right now is the final Arab/Israeli war as outlined in Ezekiel 38. Perhaps with Russia and Iran.
