It's no more than political posturing. The West doesn't like the way Putin, in the eyes of his own people, has restored the status and dignity of their nation after they'd been a basket case following the collapse of the USSR. The West is looking for ways to attack and undermine him, and the western nations may well have surprised him by the near-unanimity of their actions. In the scheme of things the actions on both sides don't matter very much. This time next year the numbers of diplomats on both sides will be recovering. That's how it always goes. There's been a lot of confected outrage over what might not even have been an attack on two people - we still don't know what happened in Salisbury. Save the real outrage for Afghanistan, Palestine, Iraq, Libya and Syria.
