However, the Maharal is misquoted. You can find it in ??? ????? ??? ??? ??. He writes that even if we are being killed we still shouldn�t try to break out and go against the oaths. (Not a question of Pikuach Nefesh, since it won�t help.) This was misquoted and mistranslated as if he saying that even if we are being forced, under pain of death, we still should hold strong and not violate this sin, hence those must be akin to the three cardinal sins. Check Rav Hartman�s footnotes there.
I don’t see a practical difference even with your correction regarding the Maharal. Either way, the Maharal is saying not to violate the oaths even if we are going to get killed, otherwise. Which clearly indicates the oaths are binding and they were violated by creating the Zionist State. And, arguably, are continuing to be violated.
