UK Politics

That's not what this is about. Everyone agrees that damage to military assets is a criminal action, no matter how you justify it. The problem I and others have is that the actions don't meet any sort of sensible criteria for what is "terrorism". Most people would say terrorism must involve mass harm to people, not necessarily property. Lots of other organisations over the years should have been proscribed if "terrorism" means property damage. Anyone involved in the race riots, Just Stop Oil, hell, even Banksy, would all qualify if that was the case. It opens the door for the UK government to proscribe any organisation it doesn't like, which is especially concerning at a time when the next government is likely to be even more authoritarian and use this event as precedent to do the same but more.

Depends on your goals and what you are willing to risk to achieve them. Some people throw paint on priceless art, some people light themselves on fire, some people yell at people on the internet. Any protest is a cost-risk evaluation.

Didn't they damage weapons for Ukraine, not Israel?
