How is that? How do you suppose the British government could have avoided this? You speak of Ukrainian lives, so presumably you are referring to foreign policy and not domestic policy. Through which foreign policy decisions has the British government caused this?

It's not like Britain could have kept energy prices down by not aiding Ukraine. It's also hardly realistic to suggest that British aid to Ukraine has come at a significant expense to the taxpayer, given the baseline defence spending by Britain to counter Russia.
