Due to the second Civil War and other things, there will be general devastation in the area. I read a report showing where the greatest concentration of nuke silos is in the US. Eastern MT and Missouri are ground zero in that respect. In a first strike scenario, the goal is to hit the silos first and create dust clouds that are 60,000 feet high. As the reactive missiles are launched, they rise up thru the dust clouds at mach 1-mach 4. In so doing, the dust erodes the ballistic cone on the tip of the missile and it collapses under the g loading and the missile disintegrates in the launch phase. A few missiles may make it through, but you have effectively won the first strike and can prosecute the upper hand in your battle plan. Russia will pre-emptively strike the East coast (over what, I am not sure) and they will be easily repelled. When they come again, the desolation will be complete all the way to the Rockies. The Chinese will have the West Coast - and they will be brutal.
When the Lord was not able to redeem the Saints in the first go-around due to our lack of obedience and the wickedness of the people in that area, the backup plan was to redeem it by force (the wicked killing the wicked). I think God always works to the best-case (which His children can never meet) and has the backup there for the reality. That was how the Garden of Eden was. The kids could not meet the ideal, so a Savior was provided as part of the reality and backup plan.
I have much more information in that regard and it has kind of bugged me that I have not been a little bit more thorough in that regard. The bulk of munitions plants for the US can be found in that general area, as well. So, if you are an enemy, you will target your nukes, etc where they will do the most good. Remember the munitions shortages we had during the second Iraq war? You cannot even prosecute a defensive war if you have few or no munitions plants in operation or no nuclear deterrent intact. I believe these facts will lead to some sort of destruction in that general area. It may be that the attack is from an H-bomb which would leave structures intact, but kill any living organism.
There is also another way for the Lord to accomplish the might work, which is far less obvious that I must point out. When the 10 tribes return, the orb they are on will "dock" with ours to the north. Due to the large gravitational pull of that large body coming in (read my previous posts on this topic), there will be a massive earthquake and then a rushing of waters in the northern hemisphere to the North which will literally make a wave which will sweep the resulting trash off the land (and yellow dogs, too) as it moves North from the Gulf of Mexico (in this instance). If you are not above 3000 feet elevation, there is a good chance you may find yourself in that deluge as the seas heave themselves beyond their bounds. It will be a fascinating time for those that are able to witness the effects. God has always hidden His people in the mountains. There is a reason for that.
You will have to dig in the blog for the details as I do not have time to dig it all up. Besides, there is something about easy information that makes us lazy..... Seek, knock, find, etc.
