I'm waiting for Dachs to come along and tear that to shreds...
He's welcome to try, but I think he'll agree with me that WW1 isn't an appropriate historical example.
but in the meantime may I ask you what the generation of 1914 thought the surest guarantors of peace?
That's the precedent people love to use and I have been guilty of it in the past, after all economic interdependece was very high shortly before the outbreak of WW 1.
But the political situation today is completely different.
There's no inscrutable alliance system to keep a balance of power in Europe, there's no declining empire that's losing it's grasp on rebellious provinces. I don't think there's currently a region in he world that's remotely as likely to trigger a conflic between major powers as the Balkans of the early 20th century, and the situation in Europe was made worse by the fact that all the parties in the conflict were on the same continent and shared borders with each other.
Taiwan ? Kashmir ? Even if there's an escalation, let the Asians deal with it. The USA might feel compelled to interfere, but we in Europe can just sit back and sell arms to all sides.
The middle east ? This one could be nastier if 'the West' is willing to go to war over Israel and Russia is willing to go to war over Iran, but I dare say that we are now generally more reluctant to let things escalate into open large scale warfare than a hundred years ago because our weapons have become much more destructive and expensive and because mass media makes the horrors of war more apparent to people who are hundreds of kilometers away from the frontlines.
Now I don't say there won't be a war between China and the USA, I'm just saying Europe will be smart enough to keep out of it.
And if you want to bring Thukydides up, America is not Athens and we are not Melos.
