Speaking with colleague Colonel Jeff McCausen, CBS News, about the martyrs in Iran, in Iraq, in Afghanistan, the martyrs.

And does the military take that into account as it presses its apparent advantage over the Islamic regime in Tehran?

The willingness, the eagerness, the veneration of martyrdom,

and the willingness to last out beyond the grave in order to resist. Here's Jeff to

describe something he saw in Baghdad when he was there during the Iraq war. Much more of this later.

Yeah, John, I think one thing we don't appreciate, frankly, in warfare is culture. I really think

we didn't understand that in Afghanistan. I think even arrogantly, we thought we didn't need

to understand Afghan culture. But it's that persistence that you talk about that's so key.

I can remember in Iraq,

John, during the war in Iraq, on the street corners of Baghdad, for five bucks, you could buy a DVD.

The DVD was of a suicide bomber, and it was a crude filming of him explaining why he was going to

drive this truck full of explosives into an American base.

Then it filmed him hugging his comrades, getting into the truck, and then they would put a

chase car behind it to follow that truck in until he detonated it. And then there were some crude

imagery of him going to heaven and being greeted by a group of virgins on the other end.

We Americans can't wrap our head around that. And I think the Trump administration in particular, which is very transactional

on any issue, cannot wrap their head around the fact that people will do this for that purpose.

And therefore, they may not quit, even though the transaction in material ways does not

seem to be in their favor.
