From my view this is all just affecting an air of greater naivete or wide-eyed wonder at the infinite possibilities of the future without actually considering those possibilities are really just finite. France is very unlikely to transform into a completely different country over night, for instance. But
Camp of Saints was written in 1973 and still gets cited today. The situation predicted by that book is answered by the reality of Europe today in torpedoing migrant boats to ensure that the reality they fear coming to pass never actually does.
To the point: Vietnam and Korea are not actually merely in the past. This is what Estebonrober is trying to communicate to you. We live with the very real consequences of it right now. Questions that to you may seem obvious, like "But what did we
learn from those wars?" are not actually so obvious at all. One can point to new military adventures, but supposedly one can always generate a new excuse for a new military adventure anyway. Rather we should look at the relationship the US
continues to have with these countries today. One finds South Korea and Japan hold not just a little amount of American bonds. One also finds that there is a complex panoply of economic interests that continues to bind these nations to the US' powerful interest groups today. One also finds that the US' continued support for these client states forestalls or prevents any attempts at reform, where within those countries, the real wages for the vast bulk of the population are significantly lower than those of Western nations (25% lower than the US for Japan, more for Korea). There is then the matter of currency and how Japan's being beholden to the US forces an unsustainable convergence of Japanese prices towards means pegged downwards to the advantage of western investors,
an issue well-known and talked about. This is real, and not relative. The US really does have some kind of suzerain power over these nations.
And above all, the current situation is directly inherited from the previous situation. By understanding the real story we can understand how the U.S. really interacts with these places and what the real impacts of U.S. foreign policy are. By refusing to do so, we merely consign ourselves to repeating the mistakes of the past and ensuring that no bad policy ever gets corrected - merely excused, with a ridiculous story - usually told by the people or conspirators responsible - about how "we've learned our lesson" and "we'll never do it again." In reality we seem to keep these pathologies going. Iran-Contra, Iraq-Iran, Kuwait, Iraq 2, Afghanistan, the everlong blockade of peaceful Cuba, continuous and baffling support for Israel - these things are all part of a broader pathology which was true of America in the past and is still true now. And maybe you can say it's true of all Empires. But this is the one the thread is about, and it's also the one we who live in it have responsibility for.
