Marxists see them as useful idiots
Unfortunately (ironically?) the opposite is true.
American leftists are cowards. They’ve been brainwashed to hate guns, and the femi-Nazis have castrated leftist males. These wimps need a surrogate army to carry out the mass slaughter of conservatives and patriots. So they’re playing kissy-face with the murdering jihadists, and that’s where your astute comment comes in - they don’t realize that they are the useful idiots.
The lunatics are running the asylum and those of us who are sane are going to have bear the weight of cleaning up their mess. There may not be much left when it’s all said and done but I suspect the sane will come out on top and the lunatics will be all but wiped out.
And the cycle will begin again for the next few hundred years. For the near future things are going to be dicey.
