To paraphrase the Nobel writeup: he advocated international cooperation, denuclearization, social progress, and work to reverse climate change. This was against the backdrop of a president who lied to the UN so he could depose a dictator, initiated ground invasions of two countries, had a VP who openly advertised that he was okay with doing evil stuff to accomplish his objectives - e.g. Gitmo and Abu Graib, and created a regulatory environment that led to the GFC. That prize was awarded to Obama but it was meant for the US electorate for embracing what you reductively call "hope".
