When you mention the judgements of the 7 angels in context with old testament I assume you are refering to the judgements against Egypt which are similar but not identical. The 7 last plagues will be much more extensive. Also if we look at the book of Revelation as prophetic it rules out Israel, Rome and Egypt because this is a world power Revelation !8:3 “She made all the world to drink of the wine of the wrath of her fornication. All 3 of these cities are no longer world powers and have not been for some years. The world power today is the world bank which has controlled American policy for years and other countries as well through financial assistance that comes with a price. The war in Iraq was certainly not in the best interest of the US, IT WAS IN THE BEST INTEREST OF BIG MONEY AND THEIR INVESTMENT IN OIL.
