So, in other words, a jew is condemned to hell unless he violates the pieces of his orthodox teaching he holds to be fundamental: the shema and the 1st Commandment, by accepting christ as savior.
Well, since he has no temple in which to do sacrifice; it's REALLY hard to follow the Lord's commands; isn't it!
Pardon me, but I HATE the (non-biblical) phrase "accepting Christ as savior." I think it mawkish, man centered, and contentless. That aside, why are you so hung up on Jews? All the first century Christians for the first 20 of so years were almost exclusively Jewish, and many were what we would call "orthodox" today. The great shema regarding "echad adonai" is in no way a violation of the teaching that Jesus is God. Paul would have been first in line to attest that, along with 12 other hebrews in the first century. If some modern day descendant of Abraham picks the nature of the Godhead to reject the gospel, there is no difference between that and myself rejecting it because I instinctively knew I would have to stop getting laid (at least while I was single). Both are decisions to reject an alien righteousness offered to us and to stand on our own.
