If Israel is seeking to control from the Nile to the Euphrates, why did it pull out of the Sinai in 1979? Why did Israel pull out of Lebanon in 2000? Why did Israel pull out of Gaza in the 1950s, destroy settlements and pull out again the 1980s and in 2005, etc.?

Because they were forced to. Israel is dependent on US support. If they lose their grip on the US they face an existential problem.

Given the weight of the historical evidence, Israel has, on multiple occasions, ceded land for peace. It worked with Egypt and has held for more than 45 years.

Yeah because the US has been paying Egypt off for that peace since then. Also Israel only gave up the Sinai, which they conquered in an unprovoked invasion, because they were forced to. Not because they wanted to. They were in an extremely unfavorable position.

I have never been able to understand why, when Israel's abuses in the West Bank are so flagrant and when troops of settlers are allowed to run amok on the Temple Mount, why do nutter conspiracy theorists start frothing at the mouth about Israeli plans to annex Cairo and Iraq.

Start frothing at the mouth? Really?

But I'll bite. Israel invading their neighbors is what will get the US dragged into another desert war. The oppression of West Bank and Gaza alone won't.

It's crazy. It distracts from the real issues. I'm half inclined to label the worst of the conspiracy theorists as Zionist shills distracting from everything that actually matters.

The only thing that actually matters is that Israel has de facto control over the US government and because of that is able to act the way it does. Once Israel loses unconditional western support the problem would solve itself.
