The UK has very broad terrorism legislation, but conventionally terrorism is something directed at civilians, and it's not something we usually tar, for example, resistance groups with.
I think you even have to be able to kill people in internal political conflict without being called a terrorist. There are many circumstances during which such things are necessary.
If the government wants to shut this group down (which I think is a reasonable response to an attack on our military) then I'm not sure what other options were available to them. And like I said, what they did seems to meet the legal definition of terrorism (regardless of whether that definition is a good one.)
Of all the arguments we could be having about Palestine, I'm really not going to shed any tears for Palestine Action.
But I'm not here to get lost in the weeds, I just objected to the misleading half-truths that were being presented above. Most people reading this don't follow UK news closely and might come away with the impression that the government is banning pro-Palestine protest entirely, or is making it illegal to merely "hold placards". That's an outrageous distortion, and it hardly helps the pro-Palestine cause. I couldn't let it slide.
Furthermore, I think that there is a duty, if one suspects that a capability is or may be used to aid genocide, to destroy that capability. Hopefully Palestine Action are incorrect, and targeting assets that have not been used to aid genocide or otherwise make it easier, but if they are right and the UK have actually aided genocide, then they have done too little violence.
