Final answer:
The statement is false; Pompey the Great, not Sulla, captured Palestine for the Romans in 63 B.C. Moreover, the reconquest of the Iberian Peninsula by the Spanish was both a military and religious action.
Step-by-step explanation:
The general who captured Palestine for the Romans in 63 B.C. was not Sulla, but rather Pompey the Great. This makes the statement in the question false.
Sulla was indeed a powerful Roman general and was involved in conflicts during the Social War and with Mithridates; however, it was Pompey who ultimately subdued Asia Minor, annexed Syria, and captured Jerusalem, thereby consolidating Roman control in the region.
Concerning the reconquest of the Iberian Peninsula by the Spanish, this is a historical event referred to as the Reconquista. It was both a military and religious campaign to retake the territory from the Muslim Moors who had controlled part of the peninsula since the 8th century.
