A missile defense only ‘puts you in the driver’s seat’ against countries that want to launch missiles against you. Our friends shouldn’t care, especially since we are very likely to offer them those defenses (and it’s very much in our interests to do so). Hell, Reagan was willing to give SDI to the Soviets.
Incidentally, Europe is going to fall under risk of missile attack a lot sooner than the U.S. will, because Iran will have a missile capable of hitting them in just a few years from now.
And frankly, if someone’s going to be in the driver’s seat, I’d much rather it was us than Saddam Hussein.
So many of these arguments are straw men. You guys start out with the assumption that the military is a bunch of drooling idiots, then use that as proof that they will make bad decisions with respect to missile defense.
The fact is, if the system is only X% reliable, then they will take that into account in formulating policy. This is nothing new. We constantly formulate policy based on threat analysis, estimates of likelihood of success of military actions, etc. Remember the Gulf war? Remember all the talk about how it would be a quagmire, and how Saddam would manage to draw Israel into the conflict, which would escalate the war to the entire middle east? Those were all possibilities. And the smart people in the Pentagon weighed them all and then made their decision. They will continue to do so.
No one is about to go, “Yippee! We are invulnerable now! Let’s push everyone around!”. If the Bush administration wants to move to operational deployment of the system, it won’t be because they are a bunch of deluded idiots with unrealistic expectations. It will be because they think that a defense that is even X% effective is better than nothing, or because they want to use the threat of deployment as a negotiating tool, or whatever. But at least give them credit for being intelligent, educated people. I daresay that Paul Wolfowitz, Colin Powell, and Donald Rumsfeld have more information and more experience than the denizens of the SDMB.
And yes, I’m aware of the threat of smuggled nuclear weapons, and the government is too. In fact, they issued several alerts to that specific risk in the near past. That’s another strawman. It’s like saying that we don’t need to develop aircraft carriers because the enemy has submarines, or that we don’t need tanks because we have airplanes. Different threats, different tools.
If the U.S. is forced to completely close its borders, or if it develops the strategy and technology to effectively prevent large weapons from being smuggled into the U.S., then ballistic missiles will be the only way to get those weapons to their targets, and you want to have a deterrant against it.
A good defense is multi-faceted. NMD isn’t a universal shield, it’s just one more weapons system in a very complex, interlinked arsenal.
