You are certainly right, it could be an EMP attack. Most Americans would die in the ensuing chaos.
It could also be a financial meltdown, or a cyber attack on the banking system.
Or it could be something as simple as assassination of Donald Trump (or Cruz, if lightning strikes). Arrange it for shortly before or shortly after the election. This would throw our political system into complete chaos.
There are of lots of ways to create a situation calling for martial law. Throw in a little terrorism just to make sure the pot boils and Voila! Our Dear Leader would have to step in and save us by ordering martial law. Not much risk to Dear Leader either. You could not even complain about it without the NSA knowing.
Presto! President for life!
If you are our beloved Dear Leader, what’s not to like?
Yes, they’ve got every weapon in their arsenal, and have already made provisions to be able to take away our ability to resist - which IMHO exposes intent.
I don’t think Obama wants to be POTUS for life. I think he only likes the perks such as yukking it up with “the stars” but if these scenarios play out he could only yuk it up outside the USA - most likely in the southern hemisphere where he is planning on spending November and December of this year...
I suspect that his contract with the communist-Islamist alliance that illegally put him into our White House (through criminally taking our system hostage) was for him to be a place-holder in the white House for 10 years, so that Obama’s puppet-masters could infiltrate the entire system and prepare it for an attack that would end up putting the USA out of existence. The communists and Islamists will have to duke it out, as to who gets what’s left. The easiest way to have the USA’s resources intact for whoever conquers us would be an EMP attack, and Obama has made sure it’s one of the easy options, ready at any time. They can even blame it on Iran or North Korea, if anybody has time to care about who made the big mess that’s killing everybody.
