It would, of course, have made liberals feeeeeeeeel goooood, that they had "done something", even if "something" amounted to nothing more than eyewash.
Of course, if you're a liberal, being able to blame nameless conservatives (no no, not FDR of course) for "not stopping the Holocaust" feeeeeeeels every bit as good as having "done something" which amount to nothing.
Is that clear, do you need me to explain it again?

I think it’s questionable even to assume that leftists view killing Jews as a bad thing.
