Are you ranking them only based on wars they fought and battles they won, or does it also take into account strong but unused military power? The biggest sign of the current dominance of the US military is that no one since Japan has actually tried to start a war with us, because they know that they'd lose. Of course MAD is part of that, but even without nuclear weapons our military is simply far too strong to challenge, and no one wants to go around conquering like the Romans did.
Same with England- when they were at their height they never fought any major wars and didn't even need a real navy because they could crush any other power with their navy.
On the other hand, ancient powers like the Mongols and the Romans had very strong rivals nearby who they spent hundreds of years fighting. Is that helping or hurting their ranking?
It's also hard to compare the "relative power" of modern and ancient nations, since our powers are so different. I mean the current USA army is obviously more powerful in "absolute strength" than the Mongol hordes, but then, so is the army of Luxembourg, so that's not too meaningful. Looking at the relative power, the USA can transport its army anywhere in the world, and defeat smaller countries like Iraq without losing a single soldier (in the regular fighting), which the Mongols couldn't have done. But, the Mongols had the ability to pacify conquered territories by massacring any resistors, which the USA can't do (if our military ever tried this, there would be mass rioting everywhere).
Excellent post. Although I'm from America, I'm really not an america-phile--I rather detest America--but I think you do have to give them credit for their ability to wage total war on an intercontinental level.
In terms of warfare, the ocean has historically been a more difficult barrier to cross than the Russian winter.
The colonial powers sent relatively small forces to vastly technologically inferior parts of the world, but these weren't full scale wars. In civ4 terms, it's like sending 6 rifleman in two galleons to the New World inhabited by ppl still using longbows. Now compare that to sending 100 infantry across the ocean to another nation full whose favorite toy is a tank.
Whether or not America won the following wars--WW2, Korea, VN, Iraq-- is rather insignificant in comparison to the wow factor that they were actually able to even get their and often out-perform the indiginous cultures.
What makes WW2 so remarkable is that the US possessed the capacity to fight two massive fronts across two massive oceans against two technologically equal enemies. That's quite a staggering achievement when you compare that to the previous history of world warfare. It's unprecedented.
Even today, America could conceivably make a good show at invading anywhere else in the world. Could anyone else conceivably make a good show at invading America? For that matter, has any power other than America made a good show at invading another continent across an ocean?
Not even Rome or England were able to achieve this dual sea/land power, much less on multiple fronts. Some of you might be thinking to argue for England or Rome, but truly neither force fought total wars against technologically equal foes across oceans on multiple fronts.
The European colonial powers picked on "neolithic" entities overseas, while they were all unable to gain any domination over Europe. For all of the apparent size and power of the world empires of England, France, Netherlands, Spain and Portugal, these empires came at the expense of vastly technologically inferior non-entities. None of these European potentates were ever able to dominate Europe. Again, although they appeared to possess godlike power in the far-flung reaches of the world, back in Europe they were quite ordinary. In fact, along with the HRE, Prussia, Austria, Russia, Sweden, Denmark, the various Italian states, and the Ottoman empire, no nation was permitted to gain dominance in Europe as a constantly shifting pattern of alliances worked to maintain balance. This situation never permitted any single nation to become overly powerful or dominant, which therefore effectively nullifies any arguments regarding them becoming the greatest military powers of the world, because as soon as one of them seemed to become that power, the others took them out.
Within Europe, none of the European powers were ever fully dominant, and this is a more telling indicator of their military strength than the size of their world possessions. Sure, the colonial powers could slaughter Indians (of both varieties), Africans and Asians, but they could never slaughter each other. England, while at one time maintaining the largest "world" empire, never possessed the sort of power within Europe itself that Prussia, France or Austria variously held. This must be considered as a mitigating factor while examining British military effectiveness.
Rome, at the height of its power, possessed far more power in comparison to its European contemporaries, than any of the later colonial powers did in relation to their other European contemporaries. In truth, Rome didn't have another European rival to compare with at all, you have to go all the way to Persia to find a nation that is nearly as powerful. That says something favorably for Rome and unfavorably for the later colonial powers.
To speak directly to England and France, England was more powerful overseas due to its focus on naval power, whereas France was more powerful within Europe proper due to its focus on land power. To whit, England never made any lasting territorial gain within continental Europe, and France kept losing its overseas possessions to England and the other European powers. French policy was to take Euro territory so that they'd have something to trade in exchange for their lost overseas possessions.
As to WW2. One could say of Germany that they were almost the greatest power that ever was. They would have crushed and removed Russia if they had simply done of the three following options:
1. Simply wait to knock off Russia after they completed their conquest of England
2. Simply wait to invade Russia until the next Spring.
3. Simply have invaded Russia 6 weeks earlier than they did.
Any one of these three options, and any talk of Russia being the nation that defeated Germany is moot.
Fortunately, Germany is the latest example of the shifting pattern of alliances that prevented any single European nation from taking over world domination. In this latter case, however, Europe needed a little bit of help from a non-European power to achieve this result. Any thoughts that Russia could have defeated Germany alone are simply hollow and dishonest.
In similar fashion to Nazi Germany, one could also say that France, on several occasions almost became the greatest power that ever was, but ultimately failed under combined European weight.
I'd have to rank the great powers this way.
The top five in no apparent order:
America, USSR, Rome/Byzantium, Mongolia/Derivatives, Vikings
The European colonial powers
Britain, France, Prussia
The almost Asian colonial power
Japan
The other colonialists
Spain, Portugal, Netherlands
Antiquities
Greece, Arabia,
The Home Powers
China, India, Ottomans, Egypt
Small scale conquerors
Persia, Babylon,
As to the Vikings, why hasn't there been discussion regarding all of the kingdoms they started?
They are the smallest group of any in the Civ franchise, but they started and altered more kingdoms than any other.
Contemplate the irony of the following statement: Gandhi unified more of India than any other Indian conqueror.
