Plus, Obama during his both terms dropped over 100,000 bombs on people. Prior to that he received Peace Nobel Prize - right at the very beginning of his 1st term.
In my humble opinion, it was one of the worst choices for Nobel Price winner - right after Nobel Prize for European Union, which was arguably the worst choice ever.
I am beginning to think that Obama was liked because he was more of a mascot, first black president etc. His views was actually far more utopian than Trump's and his execution was terrible.
During his presidency USA became a pushover country and not the global leader like it used to be.
