I'm left with a diminished opinion of RedState, unfortunately, as well as the article author. Some history in the link below. Palestine has been around for centuries. To claim otherwise is disingenuous at best, deliberately deceptive most likely.

Outlandish claims to the contrary are readily accepted by those wishing the narrative that "Palestine never existed" were real. The area has had a tumultuous history with a variety of conquerors, so why can't we just state that the area was under UK control in the early 1900s and it was negotiated between them and the zionists to "give the land" to them mid-century?

If the Chinese came over and seized California, then negotiated with Zimbabwe to "give the land" to them, upon which the Zimbabweans rename it to FeySoya, would we say that California and Californians never have existed?

"... After Constantine I converted to Christianity early in the 4th century, a new era of prosperity began for Palestine. The emperor himself built a magnificent church on the site of the Holy Sepulchre, the most sacred of Christian holy places; his mother, Saint Helena, built two others—at the place of the Nativity at Bethlehem and of the Ascension in Jerusalem—and his mother-in-law, Eutropia, built a church at Mamre. Palestine began to attract floods of pilgrims from all parts of the empire. It also became a great centre of the eremitic life (idiorrhythmic monasticism); men flocked from all quarters to become hermits in the Judaean wilderness, which was soon dotted with monasteries. ..."
