History is repeating itself. Leading nations will eventually collapse and get replaced by growing/rising ones.

If that's the case, whycome Eisenhower start the Interstate program after the war was already over?

Civilizations that are failing build walls.

Israel are building large walls, and I don't think (as of yet) it is a failing nation. But there is something you're touching on with walls that is worth considering. Walls aren't just a defensive tactic, they can be two way and are merely something to impede traffic.

The reason walls are presented as an option on the southern border is because the situation there is not managed. If it was, no wall would be needed. The powers that be want to people to argue about a wall all the while not empowering the nation (people) to uphold the laws themselves and become bystanders instead of participants (as it was originally meant to be). In this way, the idea of a wall is a cop out that abstracts away direct action from the population to manage their own border, or have it managed for them as they would will it.

Walls can be poorly used. The great wall of china, the Maginot line (France) and others were erected but they are just but one of many levers to pull for defending a nation (nation meaning the people). This is really the distinction. Defense of the people is key, but a wall makes the nation a land mass instead ... at least abstractly.

Observe the economic expansionism of rome and the u.s. Civilizations that are acting defensively build military bases. Observe rome, spain, portugal, britain, and the u.s. Civilizations that are growing economically build airports and other non-military transport.

It does seem likely that economic travel bases (ports, airports, etc) correlate positively to economic growth. But not sure which one causes which, or if it's a correlation but I don't know if this premise is fully complete. For example, look at Canada. They have built a few airports in that last couple of years (government funded for private enterprises, to golf courses etc.) and have no military bases of their own (or at least any expansion) as far as I can tell. However, the economy is not doing overly well at all.

Russia isn't a threat. China is.

If you're talking economically, at this time (given you're previous premises) I think you're right. However, I think fundamentally they've both been threats for a long time. It depends on what you think has happened in the last 100 years and who actually runs those countries (as in influences, controls, not the figureheads). I would offer a consideration that the mafia (and that's the best word to describe it) that influences (protocols of zion) USA, Russia, China and Israel are the same. While Russia seems to have unshackled itself from communism, what would you call China? China has currency, production, industry, different classes, capitalism, and an "unelected" leader ... as well as a controlled media. How is Russia any different?

I honestly believe China and Russia are a show and are really nations already awaiting one-world-government. The people running those nations are controlled by IMF and (at this time) believe if they participate in the creeping communism world wide that they'll be able to control their part of it. Kind of like in every major war the same group funds all sides.

The U.S. has failed politically and is slowly failing economically (everyone knew this already).

The entire western world run by WASPs (white anglo saxon protestants) has been "given away" a long time ago. I agree US has failed politically, but it's deeper than that. First we get a washing machine that frees us from laundry, in the same way we get government funded schools to unshackle us from teaching math to our children. The difference though is that the washing machine isn't paid to slowly destroy you and enslave you and your children. The similarity is, most people wouldn't believe either is nor would they be inclined to check. So, we (in the entire western world) are presented with a game board with few moves left on it.

The way out is to realize the game itself is fake and we don't need checkers to manage our laundry or educate our kids. A mass decentralization is required NOW or the entire western world will be lost. A disconnection from a global economy will require we look harder at the finances, ideological programming, and food supply. The separation effect is just making us complacent, and to bring it back to the analogy when the washing machine breaks down we won't know how to do laundry anymore.

I think this has been a plan all along to of some central big brother authority. While it seems that China and Russia are doing well, consider that these are local problems and the game is rigged. Money is an abstraction which is used to make us look away from merit. So, US is still failing but look at the morality of these two nations for a comparison. Not good.

Right now we should be in competition among the stars, JFK had a vision and Dr. Wernher von Braun they wanted America not just to beat the Soviets to the Moon, they wanted to expand the USA into space see the Ruskies left behind as the US would lead a colonization of Mars. Walls work, its what keeps pressure out in a sub, its what keeps pressure and atmosphere in within a vacuum of space, what the Chinese way back in those ancient times, what they needed back in the day was a good counter offensive against the Mongols but they mostly didn't have it and the men were too busy doing paintings and poetry. The shitlamics their mistake back in the days of the old Iranian persians, the arab Caliphs, the Khwarezmia, their mistake was attacking some Yellow Mongolid messenger from the East and sending a decapitated head back as a message to Genghis Khan, the Mongoloids took it as a personal insult and fucked up these jihadi islamics because of the insult. The fortress mentality actually works, on the chaos of the open Battlefield the at the time Mongols were the most superior fighting force seen on Earth, but as they entered Europe something new and different happened, Siege warfare, they won some fights but then castles and fortress as hard as tanks and big as mountains and the different tribe of Euros they pulled up that draw bridge, took all the foods inside, batten down the hatches...eventually the Mongols starved themselves, died of sickness, while Mongols were good at fighting they were superior warriors they knew nothing of maintaining a long term civilization. Sometimes people get fooled by trends, others taken and brainwashed in waves of political propaganda, I met all types, soldiers, artists, engineers, you also got the parasite wandering ex-pat types, they seen riches in big middle east buildings but only came back home with a small few bucks and a miserable attitude, a lot of those zio dual citizen banker types like to travel but they have no loyalty to America, just fleas living on the back of the dog, their morality sometimes worse than some hustling carnie at the fair doing a 3 card trick, in one generation the 'chosen' people you can not name they went from genius, researchers, writers guys like Einstein, they got replaced with merchants of sleaze like Weinstein and Epstein...The movements the patterns, it can change in an instant, suddenly the water is brown dirty black, no food on the shelf, 2017–2019 Qatar diplomatic crisis. So what else of mankind, the civilized, the Civilization that are falling, since the dawn of recorded time most of the dying they go to the middle east an utter shithole of Arabia, the Middle East dying sandbox and the graveyard of Empires, how did a Mesopotamia once know as the height of civilisation get so fucked up? That answer is easy it is the cancer called islam.

Looting America and Europe via money printing was the plan all along. Workers are just paying for wars, migrant benefits, and interest on printed up debt. While waiting to be murdered by colored folks.
