Just had a look through the “circular arguments”, though I think you might be wrong about who is going around in circles. You know the people making weapons aren’t part of Britain’s national security and are not military owned.
They are a private corporation making weapons that are being used in a manner that governments across Europe and the rest of the world are questioning and many are using terms like war crimes and genocide. Even Israeli soldiers have gone on camera to document how these drones are being used to indiscriminately target civilians (including children) and blow up civilian infrastructure.
The people breaking in are committing a crime - they are breaking into a corporations building, not a government building. The people who are being financially hit by the vandalism are corporations who are profiteering from the deaths of civilians. This is not a threat to national security, it is a threat to corporate’s profit margins and Israel’s ability to continue their genocide. Vandalism is a crime but it is not as reprehensible as making drones for people who are targeting civilians!
