Iron Dome, what is it, Jeff?

And do we need it and what will it do for us?

It's expensive, you mentioned.

Yeah, Mr. Trump has talked about creating an American Iron Dome missile defense field

that would uncover the entire homeland.

And Iron Dome, of course, being the name he's adopted because that's the air defense system

that the Israelis employed with

great success, quite frankly, during the most recent war with Hamas, Hizpala, and also in

defending Israel from attacks using Iranian missiles and cruise missiles.

And that being said, obviously the scale of the problem is enormously more difficult with the United States to do the vast expanse of U.S. territory.

Israel being a very relatively small country.

Well, must keep in mind if you defend the United States territory, that includes Alaska, that includes Hawaii, that includes Puerto Rico and Guam and a whole bunch of places.

So in terms of the overall

territory to be defended, a very, very significant problem. Second, it's somewhat reminiscent

of Ronald Reagan Star Wars, which was talked about during his administration in 1980s, primarily

focused on the United States from the Soviet Union and attacked by the Soviet Union.

The scale of the problem today, though, is quite different.
