The U.S. has imposed more sanctions than any other nation, and it should know by now that they don’t work. Some people never learn. From Tom Luongo at tomluongo.me:

One of the key points about US sanctions policy not fully understood by most analysts, and certainly not most pro-Russian analysts, is sanctions are not a direct political tool. In extreme cases, like what befell Russia in the days after its invasion of Ukraine, they are intended to be.
But on balance, sanctions as used by the West are a far more dangerous tool than just regime change, they are the lynchpin to long-term denial strategies of militarists and would-be colonizers.
We have spent five months now focusing on the boomerang effect of Western sanctions on the Russian economy. And that boomerang effect on the West, particularly Europe, is real and predictable. The intended goal of creating a quagmire in Ukraine which would create domestic unrest at home for Putin did not materialize.
The military quagmire is debatable, if you believe anything coming from Western media sources. I don’t personally believe much of what is said, but the relatively hard battle lines of the past few months lend credence to that view.
Again, not a view I ultimately share, but it’s one worth keeping in mind. If the sanctions have been so ineffective, why do they continue? What strategic purpose can or do they serve?
Because it is obvious that the people who crafted this sanctions package had a plan. Did that plan survive contact with the enemy? Was it wholly a failure or partially successful? These are some of the questions I want to address here.
