the fourth noble truth

Buddhism teaches us not to try to run away from suffering. You have to confront suffering. You have to look deeply into the nature of suffering in order to recognize its cause, the making of the suffering. Suffering is the First Noble Truth, and the making of the suffering — namely, the roots of suffering — is the Second Noble Truth. Once you understand the roots of suffering, the Fourth Noble Truth — the path leading to the transformation of suffering — is revealed. And if you go on that path — namely, the path of right thinking, right speech, and right action — then you can transform your suffering.
If you practice in a community, you help the community to transform suffering. And if you practice as a nation, you help the whole nation to transform suffering.
