Not really, he's just lied again and said he didn't mean to make the claim, even though he did.
I think that's the definition of a retraction, plus he posted it on facebook so that makes it especially meaningful.
If he was fully retracting, he would have just admitted that what he said was completely incorrect. Where as he's just tweaked it a bit. The main point is though that by normal standards he should be standing down as PM and arrested.
It seems to me he retracted, but I'm wondering if what he said is even against the law there. He didn't deny or diminish the proportions of acts, or praise, express sympathy or identify with Nazis. Some countries have holocaust speech laws that include other things like inciting the public, banned symbolisms, generalized hate speech laws that could cover lots of things including the jewish, and even statements like his that imply shifting the blame away from the Nazis, but I don't see that to be true in what I'm reading about laws in Israel.
