You might want to get even the basic facts right first - the pipeline in question isn't an underwater one. This would've been obvious if you actually read a news article about the incident or maybe looked at the map.

I'm not sure what your viewpoint is and how much you have been following the Baltic politics on the subject, but hushing something like this would be quite the opposite of how Lithuania has acted in the past years. They have been repeatedly warning that the Baltic countries are vulnerable and that NATO and the West should reinforce them before Russia acts. An act of sabotage would in a fact be a proof that those fears are very real.

Almost certainly, and Lithuanian government would call for more actions from NATO to safeguard Baltic infrastructure from Russian sabotage.

This was two days ago already and they say it was a rupture rather than sabotage.

Well it did have James Earl Jones, Max von Sydow and John Milius directing&writing, so it's not just Schwarzenegger.
