By the way, nuclear scientists have been saying since the mid 00s (since the days of the Anthrax letters when Dirty Bombs became fashionable again) that the concept of a “Dirty Bomb” is a complete hoax because the fissile materials inside such a bomb needed to cause contamination would dissipate within milliseconds of detonation, of course this is something the average ITV News watching speng is unaware of and its something Govts have used since the beginning of the War on Terror™ for propaganda purposes knowing full well they have plausible deniability.
In other words its a load of ole bollox. Whether or not this is a pretext by the Russians is unclear I suppose, the propaganda trench is so deep from both sides that the Ukrainians can literally do whatever they want and blame the Russians and vice versa.
