Thank you, Craig. You are right. In any case, even the authors who defend the authenticity do not interpret this text as an indictment of the Jews for they had crucified Jesus. The common interpretation in this case is complicity for having surrendered him to the Romans, that is the line of the Synoptics.
The passages in question,
II Chronicles,
1 Thessalonians and later
Matthew's "O, Jerusalem" (23: 37-39) are all familiar to anybody who does Muslim counterapologetics. (A risky business around here.) These verses certainly are used in antisemitic discourse, today as they have been in the past. None of that has anything to do with Paul.
Paul is one of the best prose stylists ever. Paul is exactly indicting "the Jews" for killing Jesus, and not as an isolated incident, but as part of a centuries-long pattern and practice which continues to inflict violence on Paul himself. Paul does not mean all Jews, since he retains a Jewish identity, and knows about the prophets because of Jewish scripture.
Paul does, however, mean some Jews, and he speaks first-hand, since at one time, he was a Jew doing what he later condemns. As far as Jesus's death is concerned, there is no Roman involvement mentioned in Paul. The first we read of that is in
Mark, who does not tell us his sources. It may have been an inference on Mark's part, as he tried to work out how a man killed by Jews ended up on a stick (as Paul tells us he did, at least once he was dead or dying).
Even taking
Mark at face value, there is sufficient Jewish involvement in Jesus' death tale to justify Paul placing blame on them. Since the
1 Thessalonians passage is not only about Jesus, "some" Jewish involvement may have sufficed, for Paul to include Jesus on his list.
Including Jesus on the list also helps the ever on-message Paul to mitigate a serious problem with Jesus' claim to the Messiahship - no "big name" Jewish religious figure noticed that Jesus was the Jewish Messiah until after he's dead. The inplicit argument, then, is "that's how it is with Jews, being rejected and even killed by them is a mark of authenticity - their own scriptures say so." That's what an indictment looks like, David. There is no wonder that Muslims, who otherwise have little use for Paul, think he's making beautiful music here.
Be that as it may, there is no problem with the passage's authenticity. The other poster relied on a well-spun English translation to gin up an almost sort-of (murky is the new clear) reference to a future-therefore-must-have-been-added-later event that simply isn't mentioned at all in Paul's Greek text. The bullshy reference-wannabe was tricked up by an English translator who thought it would help somehow.
ETA: It is at least interesting, though, that Paul doesn't mention Roman involvement in
1 Thessalonians. The sense of the passage is that his audience is undergoing persecution at the hands of Gentiles, parallel to the way that the Jewish church has been beset by Jewish hostility. There's a missed opportunity to remark on Gentiles yet again finishing what Jews started, or some such. Not a big deal one way or the other, but remarkable all the same.
