It sounds horrible to say, but the American people are used to war by now.
Ever since desert storm, that "warlord" Clinton has brought us to war in Bosnia, Somalia, Serbia, and has made serious threats to go to war with innumerable other places. And now we have been attacked on our own soil because of one place he forgot - Afghanistan. Additional wars will have some impact on some international traffic but unless we get something the size of the Korean war or larger, there will not be a huge impact on domestic traffic like there was in the gulf war. And I mean in terms of American casualties now, not deployment size. Americans are now used to large deployments.
Remember, Reagan and Bush Sr's military actions were allot fewer and smaller than we have seen since. They were not seen as "war" by most Americans. During the cold war, we were conditioned to think of "war" as something big, long and bloody. We were afraid the gulf war would be like that. And it was, just not for us. It was long and bloody for Saddam's minnions as well as for the Shiite and Kurds - the 2nd modern gulf war did not end as soon as we got out. But for us it did turn out short and (as wars go) sweet. It started to immunize us from the fear of war. Bosnia, Kosovo, Somalia, etc, etc.. all acted as booster shots. 9-11 was just the biggest booster shot of all - one so big it gave us a mild case of the disease it was meant to protect against. But be assured, after 9-11, we are well immunized against the fear of war. The planes will not empty unless they start carrying body bags from somewhere. And I mean allot of them, tens or hundreds of thousands.
Americans have finally gotton used to the fact that few are going to like the biggest fish in the pond. Whether he got to be the biggest by finding the best reeds to eat and by working hard at it...or by eating other fish is besides the point (though I think we deserve to be where we are, for what we have contributed to this world). The point is that people always look for the top guy to fall, and he is the perfect one to blame whenever things go wrong. Especially if there is no other top guy, like the Soviet Union, to blame things on. Not only that, the top fish is the one people swim to when something threatens the whole pond. When the top fish wants something for himself, people get the feeling that he is very selfish. Regardless of whether the facts of the situation indicate that is the case, and regardless of how selfish the other fish are. People think that of all top fish...it is a sign that the current one is better than the past ones if they feel free to give voice to these feelings.
Result being, top dogs and top fish are always fighting whether they want to or not. Because they are always viewed as the "great satan" by someone dangerous whether they deserve it or not. Even his "Friends" may call him a baffoon and make fun of him, or accuse him of exploiting them in some way. That is, untill the said people want to be rescued from some fix. Then the top dog is an angel and savior. Untill he is no longer needed, that is. Than he is the bad guy again. There is a reason that when a survey was done in China, America was found to be both the most loved and most hated nation. Human nature makes it hard to view the most powerfull nation and its leader as simply another human being leading just another group of human beings. Ya always seem to be either God or the Devil.
For all of the above reasons, all the fall of the Soviet Union meant for us is that we became the near exclusive target of all the jealosy of those less fortunate than us. Those that did like us had unrealistic expectations of what we could do for them. So like any top dog or alpha male, we are dragged into fight after fight.
We Americans can very nieve. We thought the end of the Soviet Union would be the end of war for us. That is why we cut down our military so much. That's one of many reasons we are so shocked that people hate us so much - we (generally) have a poor knowledge of history and an even worse knowledge of human nature. We think that if you kill a few bad guys on the top, or discredit an evil ideology, that everything will be alright and there will be no more war. The 90's and early 00's are teaching us otherwise. There is only one thing that will shock us now - it is a large war with tens of thousands of AMERICAN* casualties. Allot of us are still nieve enough to think that can't happen, and if it does air traffic will indeed plummet. But then again, if that happens we will have far worse things to worry about than airline bankruptcies.
*Like most peoples, we arn't as shocked by enemy casualties or by collateral damage. This is not because we are warmongers, it is because we are human.
