Russia - threadbanned users in OP

I don't quite understand the reasoning for not giving the Ukrainians the capacity to effectively target Russian infrastructure in kind. Bringing the war to their soil, imposing cost on the population and disruption of everyday life is an essential aspect of winning a conflict. Why should Russian be given free reign to leave Ukrainian infrastructure in ruins without suffering the same? See how the Muscovites enjoy a winter without power.

Attacking in turn a electrical and communications nodes should be a component of degrading Russia's capacity to wage war. It's standard practice for the US for example.

I don't buy the argument that it's dangerously escalatory, the genocidal rhetoric from Russia is fairly stark in it's goals. The WW2 comparison falls flat imo, as there's a clear difference between indiscriminate bombing of civilians and targeted destruction of critical infrastructure. This is already a total war scenario for Ukraine, why should Russian be given the sole authority for dictating the terms of combat?

Why not?

More like spooks. Imaginary and supposedly scary

The Kremlin perceives that the Brits are politically weak (that's not propaganda, they are) and sees them as a proxy for the United States. In much the same way as Belarus is a client state of Russia. They are not going to attack the United States directly, that's fatal. They can send a shot across the bows by exploiting Britains weakness, it would be for purposes of political maneuver. How is Britain weak? It only just skirted a financial crisis that almost (and still could) take down pension funds. This is war, it does not have to take the form of cutting fiber optic lines or blowing up gas pipelines. It can also be to insert division in alliances or divert resources away at key stages of battle. The XR/Just stop oil idiots are enough to cause disruption in the UK.

We don't know who blew up the pipelines to Germany, we can guess it is done with Americans tacit approval, and likely to keep Germany from breaking ranks. German industry is piling the pressure on their government. Having the Brits preoccupied with internal politics can work in the Kremlins favour, they don't negotiate with the EU as a political entity, it is always with nation states, that is why you see President Macron, or Chancellor Scholz in Moscow, they diss the EU representatives. Their goal must be to break or limit the NATO alliance or at least make them think twice about crossing the border in Ukraine.
