Every country has multiples of recipes to produce the C-4 Plastic Explosive (and or in the case of Nord Stream, probaly Semtex was used since it has a -40 °C to +60 temp range), for different means of usage. Also no two countries makes C-4 and or Semtex like any other country…
That is plastic explosive used by France is different than plastic explosive used by Russia and so on and so on. What would have been used to blow up the Nord Stream Pipeline, without a doubt has unique chemical differences which would indicate at least where the plastic explosive came from. Even if somewhat generalized. It still would match known recipes around the world…
The Russians are being barred because the Nordics/Germans know that they would immediately from any actual evidence determine who did it. Forensics does not lie…
Interesting right and now you know why the west is not allowing Russia to investigate the Nord Stream Terrorist Attack…
