Look at it this way:- without Obama at the helm in January 2009, American history would have been different, not just in its details but in its larger outlines. Here's what one should be looking at:
1. What was the state of the US economy in January 2009. Unsolicited answer: in the tank, in the doldrums, hemmoraging like crazy. The national debt skyrocketing, and the deficit in freefall.
2. Two wars that Obama inherited from George W., a man who should have cut our losses early in Afghanistan and never invaded Iraq. Later still, felt the need to begin nation building and the quest to democratise "Eye-raq," couldn't finish his misguided misadventures, thus being the principal causes of point 1 above. Plus the shenanigans in Wall Street through most of the 2000s prior to Obama; enter obama and his enforcement of new and rigorous banking and finance laws, including Dodd-Frank.
3. The leakages from 1+2, that left us in the hole to the tune of close to $2 billion, which by 2015 is approaching $3 billion. Yep, that is trillion with a t.
4. What's the equivalent of China's current reserves again? Roughly what Bush wasted $$$ on his misguided wars overseas.
Now let's take a glimpse at what Obama has been able to achieve.
* General Motors and our automobile industry is forging ahead.
* The debt and the federal budget deficits that are falling faster than had been projected.
* Because of the improving domestic economy and winding down the two wars (save for the ISIS issues and Yemen), we can now turn our attention towards helping folks abroad - increasing assistance and funding for energy, infrastructure, agriculture, science, technology, the civil society, health - read up on Obama's GHI - and ebola, governance, women and youth initiatives.
* Negotiating with Iran despite intransigence from the Republicans.
* Signing numerous trade deals with several countries; now turning his belated attention to the Trans-Pacific Partnership (TPP). Shinzo Abe is in D.C.
Under the circumstances and all things considered, Obama has done well for Africa and the world at large.
