Sanctions alter free markets and are generally ineffective and only distort the markets as an efficient market hypothesis states the market will work around the sanctions.

Russia has rerouted it's exports and replaced it's imports. Their budget is healthy and making record profits due to high energy prices caused in part by sanctions.

I also disagree Russian civilians are somehow innocent. Their tax base supports the government. Russia is still a democracy and they elect their government so are liable for their actions.
