Hearing the media describe Obama as being "blindsided" by the number of foreign crises and other sorts of piling-on from shockingly disloyal former cabinet members , all I can think of is (a) no one, surely, could ever be prepared to offer immediate resolution to Syria, Iraq, secret service meltdown, VA problems, Netanyahu, ISIL, Putin,Ebola, climate change, vacillating European allies (vis a vis Ukraine), all happening simultaneously, much of it damage caused by W, AND made infinitely worse by outrageous Republican obstructionism and lies, and (b) I can think of no one (at least no politically viable potential president) I would rather have in the driver's seat on foreign policy and environmental issues and judicial appointments right now than the Obama administration (including Kerry as SoS and several other administration members in addition to Obama himself).
Whatever Obama's perceived or real failings (yes, he's not perfect), I shudder to think of the alternative possibilities among other potential presidents. ANY alternative. Seriously, we are lucky to have this man as president. I only regret that he hasn't had the good fortune to have a congress that is willing either to cooperate or even to work at all.
In addition to the topics you mentioned, think also of his unheralded but important achievements judicial appointments (not just Supreme Court but federal courts of appeals, etc), Native Americans, workers' rights, etc.
