In this task you will be given a claim and a perspective. You should determine whether that perspective supports or undermines the claim. If the perspective could possibly convince someone with different view, it is supporting, otherwise it is undermining.

 perspective: A long ruling and ruthless dictator was toppled.
undermine

support
