It's at least theoretically possible for this to become a general pandemic. Some consequences absolutely follow, IF it does:
1. If it's out of control in the US, it's out of control in Europe and Asia as well.
2. If it's a general pandemic, nobody will provide any more aid to any part of the current region that shows even sub-epidemic levels of spreading. The whole rest of the world will be dealing with the problem in their own backyard, unless and until someone gets a real breakthrough. In a pandemic, it won't be worth analyzing whether to give more or less support to countries such as Nigeria which claim to have gotten a measure of control. In a general pandemic, debating how relatively effective Sub-Saharan governments have been is the very first thing that stops mattering.
But, right now, it's pretty far from a general pandemic,and given the virus is not of a class that has any significant potential to become airborne, it doesn't look all that likely. So some consequences follow in the same way:
1. It makes sense to fight the disease over there instead of over here, in much the same way as it theoretically does Terrorism. In fact, since Ebola isn't sentient and can't adapt to counter an announced strategy, the "Over there instead of over here" strategy makes more sense than in a human v. human war, not less. If we're going to discuss this in terms of left and right, my question would be why isn't the right comfortable with the same strategy it's been pretty insistent upon in other circumstances? That lack of consistency makes me suspect the right is simply saying whatever the Obama administration chooses is wrong.
2. If point 1 is true, then it does matter to decide if certain parts of the region can benefit us more than others to help. That's standard triage - you expend resorurces where they may make a difference. There's little point in helping a nation if they can easily get the disease under control by themselves, or if there's nothing else that will work except letting it burn itself out, but great potential value in helping those locations where getting treatment there will stop people from spreading it around further.
3. This takes military style intelligence gathering, to know how much of what various regional governments are claiming, is actually reliable. The US may face a real problem in deciding what to do, that stems from not having spent our Intelligence dollars wisely. The people pointing out that South Africa has instituted a direct route based quarantine and is currently ebola free might want to note that South Africa has a very high HIV rate and was reporting they had little to no problem with HIV not all that long ago, that many other countries are currently ebola free and have not implemented quarantines, that South Africa is heading into local spring warming while the northern hemisphere is about to cool off for fall, and many other factors, in deciding what to do and what may or may not be expected.
