That made me laugh. Care to enlighten us what barbaric stuff Stalin did, what Lenin did not
(or to put more correctly: what barbaric stuff was being done in Stalin times and in Lenin times).

a quick note, to take some options from the table: concentration camps existed in both Stalin and Lenin times, and are even older. I don't know who invented this concept, but if I am not mistaken, they were already known as concept and operational in Anglo-Boer War times (~1900ies)

Mixing up a hodgepodge of cryptography-related words is no recipe for describing a good security system for securing anything.
Do you even understand what you've written in your two sentences?

Hmmmm, time to short France's bonds....... Oh boy, it's gonna be fun

Um, buddy, you'll have to up the weight of your gorillas :).
Hundred pound gorillas are not that impressive

WRONG.

Any grizzly bears, wolves and cougars, who are misfortunate enough to find themselves near migratory path of this mass of people would be EATEN.
Such a mass of people in need would strip the land bare.

Such things are not theoretical but do happen - e.g. in the past army campaigns....

Ah, you think in the right direction here my friend, however there is one more step you are missing.
Actually those 300m people could get to US (provided that there is enough water along the route) if they resort to cannibalism.
In such setup quite a few people would get through, eating their fellow-travelers.

It's a little bit like a rocket equation - rocket goes up, carrying rocket fuel and spending that rocket fuel along the way.
You just need to plug the right constants into equation.

I would SWAG that some 50m (1 out of 6) would get through to USA.
