With the Russian minisub equipped SS-750 confirmed near the Nord Stream sabotage sites on September 22nd 2022 further evidence points to Russia's involvement.

And the Russia theory of Nordstream explosion gets a boost.
Apparently a minisub equipped Russian ship with turned off AIS was spotted near the explosion location few days before it happened. Denmark probably has photos of that.
Of note: The linked article, unlike the Twitter thread, notes that there were both an unspecified number of U.S. military ships (as well as at least one helicopter) and a total of six Russian military ships in the area (including the one pictured in the tweet), all of which had deviated from standard travel and patrol routes to spend time in the area around 21-22 September. This, in turn, prompted multiple countries - including Sweden, Denmark, and Germany - to send military vessels, as well as additional military aircraft from Sweden and Poland, to check it all out. The provided images of the Russian ships were taken by a Danish patrol ship.
In short, based on the data provided in the article (but mostly missing from the Twitter thread, for whatever reason), if the Russians were indeed responsible it would appear the U.S. was fully or partially aware of it and either refused or failed to intervene, or cooperated with the operation. Unfortunately there is not enough information in the article to tell what was going on between the Russian and U.S. ships, nor which group was actually responsible, if either, and the Danish military is stated to (unsurprisingly) have refused to answer questions on the matter. It is noted, however, that the composition of the Russian ships made them well-equipped to carry out the sort of underwater operations necessary for blowing up Nordstream 1 and 2, but there is no corresponding commentary on the composition of the U.S. ships nor whether or not their AIS was active, which is rather odd under the circumstances.
From the article (assuming the information given is accurate, though sadly incomplete), possibilities include:
A) The Russians did it and the U.S. was fully or partially aware of it but refused or failed to intervene.
B) The U.S. did it and the Russians were fully or partially aware of it but refused or failed to intervene.
C) The Russians and the U.S. did it in a joint operation.
D) Somebody else did it and both the Russians and the U.S. were fully or partially aware of it but refused or failed to intervene.
E) All the Russian and U.S. military vessels were in the area at the time for completely unrelated reasons (Yeah... Okay...)
Guess we'll just have to wait and see.
