I believe it goes something like this, globalization has led to the increase gap in wealth between the 'west' and the 'rest', resulting in a socio-economically motivated hatred, combined with other wonderful aspects of geo-politics, history, and religion, resulted in 9/11 attacks, and the overall rise of Islamic fundamentalist terrorism. And then TSA.
Of course in any real analysis of the world, something as sweeping and far reaching as globalization will certainly have some effect on whatever events occurred in the previous ~10-20 years.
According to Wikipedia, globalization describes the process by which regional economies, societies, and cultures have become integrated through a global network of communication, transportation, and trade.
I'd say air travel plays a big part in facilitating that process. A case could be made that because of globalization, airport security was needed in the first place. Back in the thirties, when air travel was reserved for the happy few, airport security wasn't as much of an issue as it is now.
