You forget e.g. Mesha stele (Moabite stone) dated c.840 BC that verifies House of Omri, or Bubastite Portal from Karnak that records the conquests and military campaigns in c.925 BC of Shoshenq I (biblical Shishaq) and mentions several cities in the kingdom of Israel (including Megiddo). And many, many others. As you can see, there’s a definitive continuity here, even though the exact years are still disputed (then again, the dispute deals with circa 100–150 years to the past). All in all, the kingdom of Israel is a well established fact, and the only thing that’s really discussed is existence of Davidic dynasty and kingdom of Judah (earliest known record of the name Judah is dated c. 733 BC — Nimrud Tablet K.3751), and actual status of Jerusalem in that time (not its existence — the settlement dates back to 4500–3500 BC and the first known mention of Jerusalem is dated c.2000 BC).

My personal take on Exodus and Conquest is that the former certainly did not happen on the scale it is described in the Bible (if at all), and the latter didn’t happen at all as the proto-Israelites, as it seems, emerged from local Canaanite population way before 1000 BC (and never left en masse). And as I repeat ad nauseam — Jewish myths have more in common (sometimes to the point of identity) with cultures in northern Levant (Sumerian, etc.), than anything else. And I could go on and on. Thus, while I can agree that Tanakh (aka Old Testament) is in huge part most probably a work of nationalist propaganda, as far as I’m concerned, Salibi (whatever is his motivation) tried to create sensationalist controversy where there is none (and in a pretty dubious way to boot).
