Maybe. IMHO, It might be the code for a formerly liberal Democrat who suddenly woke up and discovered his politically correct old Left former fellow travelers were hot to sell Israel down the river.
So maybe it's more accurately code for "a Jew who got the wake-up call." In my limited experience, the classic Republican social and limited government agenda may not immediately be their preferred tonic. However, I am a "big tent" Republican and for Israel, so they're very welcome while we work on whatever's left of their formerly Liberal tendencies.
And OTOH, what really matters is winning the fight to the finish against the present phase of the eternal Muslim drive toward conversion of the world. Survival first. Politics later.
If you look at the history of most of the Jewish neocons usually cited, look to the 80s when we had a neocon President, you'll see that the wakeup call related to the spread of communism, not Israel. This is something that's difficult for the nutballs to work into their conspiracy theories, so they ignore it. You're correct that social issues aren't a factor, it relates largely to foreign affairs.
