Does Obama have any lasting contributions or successes whatsoever?

The farther we get from the end of his presidency, the more it looks like most, if not all, of his signature achievements were nothing but smoke and mirrors meant to boost his image during his presidency, but that do not stand up in the long term.

Let's take his signature achievement: Obamacare. In less than eight years, it is in danger of crumbling under its own weight and even Democrats are openly talking about "fixing" healthcare AGAIN. His plan is not economically feasible and, one way or another, will have to be overhauled completely if not ditched entirely.

The Iran Nuclear Deal. This was supposed to be a monumental step toward stabilizing relations with Iran by essentially paying them to not develop nukes. Before the ink was dry on the deal, Iran was already developing operational nuclear technology, no doubt burnished by the funds paid by the US. In the near future, Iran will be a nuclear-powered Islamic state that will be combative with the US and will ally with Russia.

North Korea. Today Susan Rice echoed the position that Obama maintained for his entire administration: that of appeasement of North Korea and ignoring their ever-increasing hostility. The country is now at the point where it is openly conducting nuclear testing aimed at US interests. Within six months, the Trump administration was able to coordinate UN sanctions backed by both Russia AND China against North Korea, something that had not been done in eight years.

Libya. What hasn't been said about this clusterfrick? Obama already admitted it was the worst mistake of his presidency and his chair has barely cooled. The involvement in the overthrow of Qaddafi not only gave ISIS a stronghold, but set off a massive tipping point for the migrant crisis that infested Western Europe.

Syria. The Red Line. LOL. Obama watched while Assad attacked rebels with sarin gas and got walked all over in diplomatic terms. And just as with Libya, ISIS found fertile ground in Syria and grew exponentially, only recently being fought back.

Stimulus. I don't know how to define this other than one massive, public payout by Obama to his supporters and donors. Shovel Ready Jobs. Solyndra. Billions of dollars, all with nothing to show for it.

Please let me know if I am missing anything. I would legitimately like for someone to point me to something, just one thing, whether domestic or international policy, that was enacted by President Obama that in the long run will be deemed a success.
