The big war (not the Iraq campaign) isn’t over. We have continuing problems in Afghanistan and Pakistan, but we’ve suppressed our enemies for a while in most places. However, eventually we are going to have to fight large battles again, because our enemies will eventually attack us in a way that we can’t ignore. I suspect that we are now in a situation like that of Israel, which has never been allowed or willing to defeat its enemies decisively and so has to fight a major campaign every decade or so. We will probably have to keep fighting until we develop the political will to win decisively. This is going to be true no matter who is President or which party is in charge in Washington.
One counterexample to my speculations is Korea, where we have been in a mostly peaceful stalemate for more than fifty years. And there are always conflicts simmering around the world that rarely do us harm. But North Korea is an isolated regime that seems likely to fall apart eventually. Radical Islam is a much more distributed, dynamic, ambitious and aggressive enemy that does not seem likely to stop fighting unless it is defeated. Remember the anecdotes that suggest that the Syrians and Iranian mullahs and Hamas want Obama to win? The usual assumption by Obama critics is that Hamas et al favor Obama because they think he’s one of them. I suggest that they are favoring him because they think he’ll pursue policies that will make it easier for them to defeat us.
In the old days America could walk away from wars, because most of the costs of our walking away would be borne by non-Americans. Technology has removed this security and we should update our sense of security accordingly. Most of us haven’t, or have become complacent, because 9/11 now feels like distant history. But the metaphor of distance is misleading here. We are not physically more distant from threats; advances in technology and in the technological sophistication of our enemies may even make us more vulnerable. Like it or not we are probably going to be at war for many more years, even if it doesn’t feel like war most of the time.
