I've heard one theory say that the blue strip is a tear-off guard.

The left side of the bill is the standard fiat bill, with the sham Federal Reserve seal.

The right is a gold-backed dollar, which is why it has the gold foil, and has the Treasury Seal, which still has Executive Authority.

Benjamin Franklin, according to this theory, was a traitor when he signed the bankruptcy drafts that gave the British Crown, through the Postal Service, an avenue to reclaim the United States should the US ever default X number of times.

That's how it goes, anyways.

Too many schemes are in play right now, you can never tell who is really in it for the people or just the same old bad actors trying to offer a controlled replacement as their rear guard is getting chewed on by the dogs of war.
