In what way has Russia chosen to brush off the warning? Meanwhile, any proxy group can claim responsibility, the fact that you treat that as some sort of evidence says volumes. One of your regime’s top ghouls went on TV and promised to conduct acts of terrorism in Russia. Now we’re seeing acts of terrorism being conducted in Russia. These are the facts of the situation.
The fact that internet trolls are now trying to paint this as a conspiracy theory is just the repeat of the Nord Stream nonsense. Your regime is famous for doing precisely these sorts of attacks buddy.
