For instance, the judicial branch of the government chose to ignore the direct law passed by congress. Not the same problem as Germany at all.
If you wish to avoid another circumstance where a Halocaust can take place, you must preserve the law and use that law to eliminate that possibility. Asking our executive to actually become like Hitler and ignore the law will not accomplish that.
Asking our Executive to oppose the judge who had already begun to act like Hitler would not be a problem, IMHO.
True, the Executive could take it too far. Then we would have a similar problem to the one we have now, just with a different branch. I think, however, we could have counted on the current holder of that office to not take it too far.
Apparently, that wasn't the problem.
Shalom.
