McCain's Hundred Years
Republican presidential front-runner Sen. John McCain on Thursday defended his statement that U.S. troops could spend "maybe 100" years in Iraq -- saying he was referring to a military presence similar to what the nation already has in places like Japan, Germany and South Korea.
Now, there is little question that his comment is being taken somewhat out of context to attack him. He did say he wouldn't mind them being there for a century so long as they weren't being killed or injured in attacks. On the other hand, he hasn't bothered to mention how long he'd keep them there while they are being attacked, injured, and killed. Other comments indicate "indefinitely", so 100 years as shorthand isn't entirely invalid.
But even if you take him at his word, that he meant he foresees a presence similar to the one's in South Korea or Germany, he doesn't actually come out that well.
The missions in those countries, like the one in Kuwait and Saudi Arabia until recently, were designed to help defend those countries against a conventional military threat from their neighbours. The only conventional military threat facing Iraq these days is from the Turks, who, thanks to their being NATO allies, are now getting assistance in their military campaign from the US itself. Anyone who thinks Iran is a conventional threat is just plain delusional. Not only does it spend only a fraction of what the other Gulf countries do on it's military, but it already has vast influence in Iraq thanks to it's connections to groups like ISCI and other Shiite powers. An actual military incursion would be counter-productive.
No, the threat, as McCain also mentioned, are non-state groups like al Qaeda and the instability they cause. Rather than being in Iraq to defend it form outside conventional threats, he wants US troops there to defend it against small, informal, and more often than not, internal, enemies. The last time the US tried that was in Vietnam, and you don't see too many US bases there anymore, now do you?
You can't claim to want to deal with a non-state force and then use missions based on state-on-state conflict as your model, unless you're not aware of the differences. And if you can't see the differences, you definitely shouldn't be Commander-in-Cheif.
