Opposed? Lehi’s members became big politicians in what would later become israel.
I have slightly edited my previous comment to include a bit more detail but here’s israeli Prime minister and leader of what used to be Lehi Yitzhak Shamir
There’s much more. What’s important to know is that Lehi while not the biggest organisation they were extremely violent. At the time they had massive impact on the direction of israel. Their radical Zionism played a big part in shaping israel and their “the end justifies the means” approach can clearly be observed to this day.
