They may not be jewish, but they will certainly serve the jewish interest. This is all by design to counter the fact that the goyim have noticed jews in the administration too much. By using shabbos goyim instead of jews, the jews can say it was all just antisemitic White supremacy to suggest that it's always jews while still getting exactly what they want. Additionally this is to sucker White men into going to war for the jews again. It's all just an illusion. The unseen hand will still be 1000% jewish.
