I find it rather comical that it is factually pointed out that the sanctions on Russia have been working
It depends on what was the goal of the sanctions. If the goal was to make lives of the Russian people harder, than yes sure it is much harder now.
If the goal was to make Russian aggression in Ukraine stop than I am sorry to inform you that no, nothing changed.
Oh, and, just in case, the biggest blow to Russian economy was not from the sanctions, but from the huge drop in oil prices
. And that blow wasn't delivered by Obama. It was the blow that was delivered by the American oil industry, fracking and all those things Obama hates so much, but just can't prohibit, since it doesn't happen on federal lands.
...and your response is to go with “blindly following” and “naïve.” Maybe in your world it isn’t possible to consider one thing positive and be negative on something else. However, I happen to live in the real world.
And in that world of yours the Russian aggression stopped, didn't it?
