What's wrong with Missile Defense? lots of good jobs servicing and building all the sites the Yanks install at their cost? If the WW3 hits all the missiles gonna fly over us anyway--might as well stop them as soon as possible. So what if it's not 100% accurate or effective.... you would rather have entire attack of missiles hit us (Canada and U.S.) instead of say even 50%? Please explain how I am wrong...
As I noted on page 5, there are several.
It isn't cheap and the political will to spend potentially TRILLIONS of dollars on it aren't there. Even with supercomputers, scaling up a system to stop a mass launch is going to cost far more than the countermeasures would. Such an arms race could bankrupt the USA, which doesn't really have its financial picture very stable right now.
Another problem is that it may start an arms race with other countries (specifically China and Russia). Depending on the system's effectiveness, they could build dozens, hundreds or even thousands of additional boosters to negate its effects. Then the US us caught in the ultimate catch-22 where they need to build more anti-missiles, which cause opponents to build more ICBMS...and so on and so on.
Additionally, there are questions over how capable it is. While I agree that technology has certainly improved from the 1980s, I don't think it's anywhere near the 100% mark. Just look at the Patriot as a case study. Everyone was told how great it was, but the reality was that even though it hit almost every Scud targeted, many Scuds still landed and did enormous damage. Nukes are area effect weapons and unless the system is 100% effective, there is still the possibility that a nation could fire a dozen missiles and take out a city or two. So while it's great that your strategic force largely survives, the effects on those cities (and their inhabitants) is just as serious.
Having said all that, I'm not opposed to the US funding it themselves. Just don't expect a cheque for $50 billion from Canada (like they are for the F-35) for it.
