> Russia started somewhat bombing civilian dual-use infrastructure only after Ukraine started bombing random warehouses in Russia this summer.

Russia bombed Ukrainian infrastructure since the start of the war. Power plants were frequently targeted last winter. The only reason why Russia is more successful now is because Ukraine is running out of advanced air defense.

> Russia could've made whole Ukraine in a literal dead state long ago -- it only takes few rockets to permanently knock out nuclear power plants and water treatment plants. Yet they didn't. I wonder why.

Because Ukraine would strike Russian nuclear power plants in response? Also, political fallout (in addition to the nuclear one) from targeting nuclear power plants would be massive. Sanctions from China and India would be on the table, which would quickly send Russian economy to the gutter.

Who started this war again?

It's because Russia doesn't want to take over a complete wasteland that will be unproductive for decades if Russia ends up absorbing all of Ukraine.
