Regardless of this specific 'glitch' and whether or not it will be resolved, the overall concept of MD is seriously flawed.
It requires an embarrassing amount of financial resource (which is by no means in surplus) to address an extremely limited (and guaranteed to be obsoleted but not due to the technology) aspect of national security.
There are so many other risks that will go unaddressed (not to mention shameful national social conditions - illiteracy, medicare, poverty).
There are numerous existing and emerging potential threats that are likely to take the spotlight, and the proposed MD expenditures (bottomles money pit - like the IRAQ war), while constent with the irrationality of a war mentality, are disproportionate to the actual problems it attempts to 'fix'.
Even if they figure out how to jump start their stalled wagon - the whole concept is insane.
It takes a lot less resource to prosper through goodwill than to defend oneself from the consequences of building badwill.
