Didn't work in the Reagan era, and its still not practical.

I went to NM Tech. Home of the US Center for Explosives Technolgy Research, the Navy's Terminal Effects Research Project, and the operations center for the VLA radio telescope. Where do you suppose most of my classmates in physics went to work? Sandia Labs, Los Alamos, various other defense contractors all working on parts of Star Wars.

The amount of fakery that went on even then is astounding (and remains unreported).

Besides which, missiles cost real money and the current crop of have-nots is a decidedly low budget crowd. They're a lot more likely to borrow a freighter and blow it up in Boston Harbor than spend money on expesive rockets. Heck, these guys took out a US Navy warship with some fertilizer and a rubber boat.

Missile defense is a waste of money.
