In fact Khaldus was writing as Christian Spaniards were engaged in a bloody Reconquista that they felt was a completely Just War by Augustinian standards.

And it was. The Moors they were fighting forcefully invaded their territory, stole their lands, and waged war upon their existing sovereigns. Spain's response meets the characteristics of a just war as (1) Its sovereigns - the various kingdoms of Spain - were the preexisting government authorities, (2) its cause was the expulsion of a foreign invader, and (3) its intention was the restoration of lands that had been stolen from it by that invader.

The Moors they were fighting forcefully invaded their territory, stole their lands, and waged war upon their existing sovereigns.

No. The Moors they were fighting were descendants of the Moors who invaded Iberia six centuries prior.

(1) Its sovereigns - the various kingdoms of Spain - were the preexisting government authorities,

A spurious reading of the past. Which of these states continued to exist?

its cause was the expulsion of a foreign invader

A spurious reading again. The "foreign invadeders" were 20th-generation descendants of the Moors who invaded.

its intention was the restoration of lands that had been stolen from it by that invader.

Spurious again. By this logic, it would be Just War to drive the Afrikaners out of South Africa, the Anglos out of Texas and the Jews out of Israel.
