Mr Kiver is living in a dream world.

None of the GMB tests have been realistic.  Any attack would feature hundreds of decoys and scores of incomings.

Right now the U.S. has about 44 GMDs ready.  Most of them are in Alaska;  it is reckoned that 5 GMDs would have to be launched to stop one incoming, given the 70% failure rate of GMDs.

Moreover, with the deployment of  long-range hypersonic cruise missiles, the GMD, Harpoon, Aegis which are not particularly good now will become completely obsolete.  The Zircons can be fitted with a nuclear warhead and variations can be launched from freighters as well.

Also, the GMD is ineffectual against satellite launched nukes.

In sum, like the USS Gerald Ford class carriers, the GMD is a hopeless $40 billion travesty.
