Okay, you all need to take a deep breath. I mean a very deep breath
The world is no longer divided into countries my friends. Nation-state globalization has pretty much ensured that a nation state now has to operate on multiple levels, including ngo's and ingo's, not to mention such far-fetched concepts as global justice and global citizenship. Therefore, talking about which country is stronger, is completely and utterly ridiculous. You can never, ever prove that one country IS stronger than another. I will of course, give you an example.
Let us presume that the United States is currently the most powerful military force on this planet. In terms of military spending, its budget is about ten times higher than that of the next high-spending military nation (China). Does that mean that the United States is stronger than everyone else? Not at all. The US economy (the very same economy that funds the military) is highly dependent on overseas imports and exports. Even more detailed, the US is highly dependent on foreign investment. If you want me to put it bluntly - the United States would go under if it were not for rich mini-states. You all seem to forget that the United States was recently 'rescued' by foreign sovereign-wealth funds. For those of you who don't know - America was pretty buggered late 07, early 08. The credit crunch affected major US based investment banks, and here I'm thinking of Citi-group and Merrill Lynch. Their debt to private US-based investors came to around 21 billion dollars. Who provided the money that rescued those banks? Singapore. Kuwait. South Korea.
If foreign states did not provide that money, the US would have easily faced another great depression - but of course, it didn't. Because it is in no one's interest to see the US go under - it has too much financial promise and gain for it to be allowed to sink.
Now take that concept and apply it to the middle east. No, Iran isnt about to go and do something really stupid, because it would lose international support, and would be completely buggered. The same applies for the rest of the middle east.
In fact, I like to think that the people in charge of middle eastern states are a WHOLE lot smarter than most of us. Which is why of course, they're not just going to sit by and wait for the oil to die out. Instead, they have began investing the money obtained from oil into creating alternative sources of money. Best example is Dubai of course - most rapidly developing city in the world, with the highest rise in living standards and business potential. You just open up any issue of The Economist, and check out some of the employment ads. About half of them are for high-ranking managerial positions in universities, banks, and corporations being founded in the middle east. By the time the oil dies out, it won't matter anymore - because they will have switched their income sources to more 'renewable' ones.
