This whole "voting for Biden is approving genocide" line is insidious since many Americans don't pay enough attention for foreign policy. They feel insecure about how little they know, if they are conscientious people willing to (rightly) question US military policy. They think: "Maybe the right move is to not be a part of it."
It would *feel* better to not be a part of it. But, that is all. It feels better.
Use every lever of power you can reach. Abdicate nothing.
