> For the whole world? Really? What parts of the world, exactly?

Every last part of the world, with very few exceptions. Let's take a few examples:

1) Africa

Before European hegemony africa was the slave hunting ground of muslims (given that the orders were given by the muslim "pope" (caliph), I think this is fair to say). It was desolate, and there were constant attacks on villages to kidnap "black gold" (slaves) into the Ottoman empire, mostly to work (and die) in mines. Any amount of progress by the black villages was militarily exterminated in a matter of months to years.

Then, under European leadership after WWI, you have colonialism in Africa. I assume you know what was wrong with that, defending socialist viewpoints like you do.

Now, under American hegemony, and largely thanks to constant American milirary and economic support, and just plain free food, there's a large number of democracies, an >1000% improvement in money earned for the people living there. I wouldn't say it's stable but it's definitely an improvement.

2) India

Before WWI, a lot of Indian territory was being repressed and under constant genocides from muslims attacks, initially from the middle east, later from the region currently more or less known as Pakistan.

After WWI, British forces took over and administered India. Whilst I'm not quite ready to say this was a universal good, it was a definite improvement over the previous situation. This united India like it had never been united since over a millenium and built the state infrastructure that made the current India possible. This changed the life of 10-20% of India from subsistence farming to an actual reasonable existence.

Then, of course, Gandhi happened. Needless to say, given the chance muslims immediately tried to restart the previous situation, (read wikipedia's "partition" article) and failed (though they succeeded in Pakistan and Bangladesh). With American (mostly economic) and British (mostly military) support the current India was created : the world's largest democracy. It was recently celebrated that 50% of India has been lifted out of destitution.

We can go on if you like, but ...

Do you really believe the idea that liberals espouse, that forward progress happens automatically in all circumstances because the clock is advancing ? For the love of God, read some history, hell, you could just read papers of today, and you will quickly realize what role American power plays. Answer me this simple question : what would have happened in Eastern Europe if America didn't have nukes aimed at Moskow ? The short story : Germany would have a Russian border right now, which would be armed to the teeth. That would have destroyed the economic progress in Europe of the last 30-40 years at least.

Now imagine not just that one event, but like a reading of 20th century history will tell you, an event like that every 2-3 years. Can you imagine what would happen ? Can you imagine what would happen if Russia, or China, or Japan, or ... had global hegemony ?

> Globalisation, unless EVERY single nation on Earth adopts isolationism both economically and socially, is unavoidable.

Do you really believe that ? Allow me to introduce you to a simple concept : a gun. Answer me this : why isn't the Central African Republic exporting loads of fish ? Do you think the problem is isolationism ?

To read about a worst case scenario, read about the downfall of the Western Roman Empire, and the rise of islam and piracy and constant genocide in the centuries following that. It will show you what can go wrong with globalization, and it will show you how long such a problem takes to fix. I'd say we're about 1400 years after these events and we still haven't fully recovered. Or at least, certainly northern Africa hasn't recovered to the point it was at in 450 AD.

But generally look up the situation at the end of the 19th century (that's 120 years ago, not exactly an eternity), and ask yourself why globalisation didn't happen, despite America, and quite a few other countries, really, really, really trying to make it work.
