A lot of people in Europe and the UK are already struggling to pay bills. It's been described as "eat or heat", since some can't afford to do both. Rising cost of living, reduced job security, and lower wages are all killing tens-of-thousands of people already.
You're treating an aggressive war in Europe like a minor calamity. It is an obvious responsibility of the state to help people pay for substitute heating and ease the negative impact of conflicts like that. In the worst case, even the military could step in. Helping citizens in times of conflict is one of the primary functions of governments and state institutions. It's much better to face these kind of negative consequences now than to embolden a dictator and later wonder why you sit in a bunker while Latvia or Poland is overrun. Just because this is not an armed conflict (yet) does not mean it should be treated lightly.

I have absolutely no idea why you say this, and I can assure you that I am not doing this.
Fuel poverty in Europe and the UK are among many reasons why those nations should take what's happening in the Ukraine very seriously. My concern is that the ruling parties don't take these things seriously enough.
To reassure you: I completely agree that states should look after their citizens who cannot eat or keep themselves warm. Unfortunately, this demonstrably does not happen.
The situation in Ukraine is dreadful, and I certainly do not think it is minor. Quite the opposite.
