They should be locked up, but not for terrorism. Terrorism is about frightening people to manipulate them. This is more like state level vandalism. Also their stuff should be seized to pay for the damage.
Why not? Using violence against civilian (infrastructure) to achieve political goals… seems to fit.
Sure you could argue violence… my take would be if you are using an oil tanker to drag a few ton piece of metal with the intent to break stuff… it’s pretty violent.
because nobody is frightened and will change their political views or anything. there is no terror. it’s just pointless stupid vandalism by a moronic nation.
People being frightened is not needed. If it aims to affect political change (which it does) through violence (which it is) it is therefore terrorism.
