Ukraine could threaten both Russia and Europeans to blow up or simply shut down the pipelines passing on their territory if Russians get too aggressive and if Europeans do not convince Putin to calm down. Why don't they do it?
- We don't know what they are warning in private.
- With Nord Stream 2, there is enough capacity to bypass Ukraine. (That's what ex-President Trump's rhetoric got wrong a couple of years ago. Nord Stream doesn't make Europe much more dependent on Russia, it makes Europe and Russia less dependent on Ukraine.)
- Transit fees are a significant income source for Ukraine. Blowing the pipelines would remove this potential for years to come.
