"Missile defense" still doesn't work

As the article explains, the answer to what I've quoted is still very much a big fat "no."

But given how far computers, drones, and laser technologies have come since the Cold War era, one might think that advanced technology could deter a nuclear weapon threat. Indeed, back in 1983, President Ronald Reagan announced the initiation of a program — derisively called "Star Wars" by critics — by which America could protect itself from ballistic strategic nuclear weapons from space.

Yet it's been 39 years since that announcement. So, are we there yet? In other words: if a foreign nation's military did, say, launch an intercontinental ballistic missile (ICBM) — meaning a missile with a minimum range of 5,500 kilometers — could the U.S. or another country block or intercept it? - Salon
