I think there is an interesting parallel with the Cold War. In comparing ancient and modern events separated by 2147 years, the overall pattern of development in relations between the leading western power and its main adversary is very similar. The underpinning theory is that the earth’s main cosmic cycle has a 2147-year long phase, which should be apparent in historical cycles. There is strong correlation between the USA and Rome as main western powers, but a morphing of correlations for other weaker powers. There may well be ancient correlations with smaller powers such as Russia and the Ottomans, but the biggest events of history have been at its leading Western edge. This is where the institutional continuity is greatest, and where we should find strongest parallels. Carthage, as Rome’s main hegemonic rival, seems to correlate to each of America’s modern rivals. The end of WW2 corresponds to the end of the Second Punic War. The subsequent 40 years in each case was a period of Cold War. In the ancient world, this period ended with Roman declaration of war on Carthage in 149BC (=1998AD). In the modern world, this period ended with the collapse of the Soviet Union in 1991 (=156BC) and the Gulf Wars (1991-). The overall phasing of war and peace between hegemons and rivals runs in parallel, and the cosmic framework of precession suggests an underlying causal link.

At other points the phasing is less exact - the First Punic War (264-241BC = 1886-1909AD) is a bit earlier than WW1, and the Third Macedonian War is ten years later in the scheme than the Vietnam War, but these are smaller events within a broad parallel process of development in which the earth’s cosmic cycle seems strongly imbedded.
