The Buddha taught the truth of suffering. Suffering arises from holding on to views that arise from ignorance of self.  Understanding (of self and all else) grows from attaining right perspectives.

So many politicians foment false fears. Fears of threats that are exaggerated or imagined. Where does that fear lead?

Fear leads to Anger, Anger leads to Hate, Hate leads to Suffering

Yoda shows the result of fear. Fear can be lessened if we see the true nature of the fear. To see clearly, we need to remove the filter of hate, and see with the clarity of love. Then we can only fear true threats. But still, love those who really threaten us.
