Perspective is all: Republicans vowed even before Obama was sworn in that he would find no support among them. They continued the birther nonsense and other malicious lies ("He's a Muslim!") even after it was shown time-and-time again to be a lie. 
So, in that kind of national landscape, could the President rescind any part of it? Imagine if he had and any attack had happened: Republicans would accuse him of a high crime.
BTW: please notice that Obama kept us safe for 8 years. No large-scale terrorist attacks on US soil. 
Repaired the economy, made the US a safe country, nailed OBL, installed Obamacare that has saved many, many lives.  NO scandals. None. 
Greatest president in modern times.
