Yeah, I do recall that. However, of course, all that leftist claptrap about the infeasibility about missile defense has since been flushed down the memory hole, and they’ve “moved on” to other lies, since then, global warming being the latest. The left glides from lie to lie, with ease.
I don't think it was just leftists. The GOPe hated Reagan, and plenty of people were making a fortune off of Big Government and the Cold War.
