Im not saying what they did isn’t illegal. I’m saying it’s not terrorism. This is like if someone was charged with murder and punished for it only to turn out all they did was rob a store and you’re like “well akshually ☝️🤓 they’re a criminal so it’s fine”
So let’s look at these requirements:
violence: not really. Vandalism and destruction of equipment aren’t violence, to my knowledge PA has not harmed or attacked anyone.
non combatants: they targeted weapon shipments and military equipment. While I suppose you could argue the UK military aren’t combatants as they aren’t part of the war directly, but honestly that point is entirely moot given that they didn’t target people.
political and ideological aims: sure, they are a political activist organization. Obviously that alone doesn’t make them terrorists.
So, even by what Wikipedia defines as the “broadest” definition, not terrorists.
I mean, at an absolute minimum, terrorism requires violence against people, which they did not do. They targeted planes and other military equipment. That’s not terrorism no matter how much damage they caused.
