The idea that armageddon will occur in North America I received from reading a book about prophecy by Roger Rusk. Revelation 14:20 says, "And the winepress was trodden without the city, and blood came out of the winepress, even unto the horse bridles, by the space of a thousand and sixhundred furlongs." 1,600 furlongs converts to 200 miles. This verse is another picture of Armageddon: the final battle. The Valley of Jezreel next to Mt. Megiddo is no where near that size. The city in this verse may figuratively be speaking of Babylon America.
In Ezekiel 39 we have, "14And they shall sever out men of continual employment, passing through the land to bury with the passengers those that remain upon the face of the earth, to cleanse it: after the end of seven months shall they search. 15And the passengers that pass through the land, when any seeth a man's bone, then shall he set up a sign by it, till the buriers have buried it in the valley of Hamongog. 16And also the name of the city shall be Hamonah. Thus shall they cleanse the land."
That does't sound like the Valley of Jezreel, which is 14 miles (northeast to southwest) and 20 miles (northwest to southeast). It sounds like some place in America, somewhere in the western part. Somewhere that is a vast piece of land where millions of men can gather for one big fight. Also, Satan hates Israel--as Revelation 12 tells us. And the "wilderness" became North America, in the ultimate sense. And the USA is the regathering of Manasseh, whom God has used to bless the world in a great way--despite the murdering of people worldwide being carried out on a grand scale by US soldiers (in the name of the Synagogue of Satan/Illuminati).
To clarify: armageddon can be seen as the war that starts with the invasion of Palestine--along with the short-lived occupation of Jerusalem--and ends with the final confrontation on North American soil--where Jesus Christ will slay his enemies.
