As someone with an undergraduate degree in the poli sciences and an emphasis in international relations, I think that the answer to the question of nuance is obvious: of course they do, that is why everything is working out so well.
I never expected GW to have any ability to do IR. He had never been overseas before becoming president, and had never studied the matter. I am stunned, however, at the hamhandedness of Cheney, Rice and Rumsfeld, all of whom should know better, or at least not be so damn offensive to those outside the U.S. Powell seems to have some far more diplomatic skills than the others, but he is clearly a weak good cop in an administration of powerful diplomatic bad cops. Our foreign policy is the laughingstock of the whole world and ill serves us.
It seems that none of the current crop have read Machiavelli, or absorbed his lessons. And I don’t just mean The Prince. Machiavelli created the nation state in The Discourses and was a farsighted figure. He understood that if a powerful leader abandons power, there is an enormous vacuum that others will try to take advantage of. (This was also the lesson of King Lear for those not politically minded.) Like it or not, post WWII earth has been either a stage for the struggle of the Cold War, or Pax Americana. As annoying as Pax Americana is to those whose feelings are tread upon and those whose rights are somehow not equal, it has always been better for everyone than any previous era of history where it was dog eat dog. As much as people were exploited, exploitation for business was far better than destruction in war or use as a pawn in a Great Power game. The U.S., for better or worse, is by far the biggest kid the block has ever seen, and was content fight only commies and do buisess on favorable terms. Had any other country tried the same (China, Japan, Germany, Britain, Rome, Athens, etc. had in the past) with a similar level of hegemony, it would be a heck of a lot uglier.
But after half a century of keeping the smaller kids on the block in line, the neo-isolationist Bush II cadre (Cheney and Rice primarily) decide to take their purist ideals and apply them outside the ivory tower, academic and partisan journal pages to the real world. The problems of places like Ireland and the Middle East are ultimately not ours to solve. But if we ignore them, they are going to boil over uncontrollably. And that is bad for the people that live there, bad for business, and bad for us in gas prices and the loss of prestige that we need for ourselves when something like 9/11 happens. By abandoning our desire to influence international events because of a neo-isolationist fashion, we lose an enormous amount of influence. Now as much as some people don’t like foreign aid and the cost of diplomatic efforts, they are a very, very tiny fraction of the cost of waging war, particulaly a war without allies already lined up.
Now the nonsense that Clinton’s effort to make peace “caused” the current uprising is nonsense. Had he taken an eight year approach along the lines of what Bush II and the neo-isolationists want, the Middle East and most of the world would now be a charred cinder. Despite impossible odds, he kept at it, and the parties believed that they had some incentive to keep a lid on it. Now, neither side believes that it is in their best interest to even consider peace. The Palestinians are tired of living in refugee camps with awful conditions and have even their small areas bulldozed by tanks. The Sharon government sees no reason to stop incursions as long as the Palestinians are making war against innocent civilian populations. The Arab League states believe that the United States has abandoned its role as mediator and has spent all week dissing the U.S. Secretary of State who is now viewed as not only a Johnny Come Lately, but as one without the President’s ear, or rather the Vice President’s ear. The President clearly doesn’t have the attention span to care about the conflict. And when GW does demand Sharon immediately pull out, Sharon says he will, says he won’t and keeps on doing it. GW looks like a weak and ineffectual leader when he has to repeat himself and is still ignored.
Frankly I’m appalled at the complete lack of sophistication of the Bush insider leadership on foreign policy. It would be nice to have the luxury of working isolationism. But we are not New Zealand. The United States represents more than half of the military power in the entire world, is the economic powerhouse and the supposed leader of the world. That requires leadership, not shirking of responsibility. But shirk seems to be the motto of this administration. If there isn’t something in it for them or their donors directly, they aren’t much interested. As P.J. Rourke, a conservative commentator, says, Republicans are the party that believes that government doesn’t work, and every time they get elected, they prove it.
