Markov. Litvinenko. Those are two other people. Not just 'one', as you're trying to claim. They were assassinated in the UK ... those assassinations also attributed to Russia.
With the latest such case, it's become clear that you won't stop. A pattern of slaughter has been established. Considering that on this occasion a military grade nerve agent was used ... this in a civilian environment ! ... a stand became necessary. And, oh dear ...your side REALLY doesn't like it, eh !!
International law, decency ... what do these matter to the Kremlin ?
The so-called 'examples' you cite of so-called lamentable actions ... how many were conducted within the context of military action, during a war ? What about dealing with terrorists ? YOU don't lament Russian bombings in Syria, and I'm sure you'd be happy to justify them. Why, then, are you critical of Afghanistan and Iraq military actions, against terrorists ?
Hiroshima was part of a World War ... AND ... it forced Japan to surrender (.. that, along with Nagasaki). Had those bombs not been dropped, for how much longer, involving how many more deaths, would Japanese aggression have continued ?
The Salisbury occurrence happened within the context, not of war, but of so-called 'peace'. Salisbury wasn't at war with Russia !! It wasn't a hotbed of terrorist cells begging to be bombed. No, your country violated a peaceful civilian community with its deployment of a MILITARY GRADE nerve agent there.
It was a truly disgusting act.
So, an international stand has had to be taken. Who's to say how many other Western territories your people would like to violate in like manner, given the chance ?
It shouldn't be too long, now, before the OPCW gives its verdict on the agent deployed in Salisbury. Getting nervous, Papokarlo ? When Russia is confirmed as the culprit, will you cut and run ? OR, will you accept Russia's role ... finally ? Even show us a measure of decency by expressing regret for your country's actions ?
In the meantime ... I note this, from 'Sputnik' News' ...
