The cost? I'm not sure when that Frontline documentary was made (no earlier than Bush's first term though) but they cited 65 billion spent on it already with projected costs to run to 200+ billion. Its the single most expensive US weapons program. And it doesn't work.

Is that just for the bush term?

Shhesh starwars was going on way back in the days of kenedy in the 60's immagine how much they have wasted.

It goes back a ways... the documentary noted that Nixon was the first President to implement a missle defence system and that the same day it went operational Congress voted to shut it down. It remained operational for an additional six months before being mothballed.

Its an excellent documentary and very informative, tracing its roots from then up until the current system the US has deployed as a "limited operational test vehicle".
