Yet UK is one of the main destinations for Russian capital to this day. Sanctions were a joke prior to 2022 and even after 2022 they still are.
However, after multiple UK citizens were harmed on UK soil calling that response "significant" anything is frankly a joke.
As I already said, personally I am afraid that we're beyond the point where any non-military response would be proportionate, but that is not what my initial comment was about.
