And I also find it offensive that major affairs like the Ukraine and Crimea, Russia's gay rights (or lack thereof), and other such things involving the killing and persecution of huge populations draw stern 'you really shouldn't do that, you know' remarks from our government and others, but one apparently unsuccessful assassination attempt on two people hardly anyone had ever heard of before March provokes immediate finger-pointing and diplomatic action on a scale not seen in years or decades. Not to say these two people are not important, but come on, more than whole populations being bombed out of their homes, occupied, or criminalised?
I agree with you every word, particularly the summary you present about having our prioritises right. I'll offer my view.
Offering a stronger stance over the Ukraine or Syria doesn't really provide a vote winner or distraction from the mess of Brexit or the other domestic policy issues the UK currently faces. The use of chemical agent on our own soil provides the perfect opportunity to hide a lot of bad news stories and empowers the Murdoch machine to hit overdrive with this 'terrible and dastardly event.'
Further, accusing Russia also provides us with chance to cosy up to our allies and presents a chance for closer links with the US as Trump can issue his own diplomatic sanctions while simultaneously taking the heat off himself over Russia meddling in the election. I can only imagine the diplomacy, but it would be along the lines of, 'Eh Mr President, you want the heat off you, we need a trade deal, how about...?' One could argue that Trump would want distance from the attacks as any support of the UK would be too obvious a ploy, but he also likes to play the 'big man.'
I believe the Conservative Party to be this cynical, particularly with Boris and Gove in the wings. Do they hold much power? Well there is a suggestion that May gave them cabinet positions to have her enemies close to her, but I also believe they hold significant influence in cabinet. She has little control over elements of her Cabinet, and needs to appease those ministers. Boris and Gove are poisonous, and still covet higher power, so use their position of being close to their enemy to maximise their political influence. They know full well they have her over a barrel. She's damned if she does, and damned if she doesn't with Boris and Gove.
Piling pressure on Russia over Syria and Ukraine with anything more than punitive sanction would be a step closer to war. Hence a slap over the wrists for them over their involvement there. The attack in Salisbury, while significant, will soon be forgotten; and the expulsions slowly reversed over time. It won't bring us to war, but has maximum political effect for the Conservatives, both domestically and on the world stage.
So yes, we have our priorities wrong, but it's politics, and it truly is awful when we see the pictures from Syria.
