Re: more of the same
Sanctions never work, until they do.
It takes time for sanctions to have full effect and that effect is cumulative.
Vaccines also take time, as the percentage of vaccinated people increase the spread slows down - this is why C19 is less of a threat now than it was 3 years ago.
As for the pipeline sabotage, the only vessels recorded as being near to the site in the relevant time period was a Russian ship with deep operations equipment.
