I partly agree. I disagree that anything we can do now will make a difference in the outcome. IMO this outcome became inevitable weeks ago, perhaps several months ago. Actually we're probably 99% in agreement.
We're watching a train wreck in slow motion. The train has already left the tracks but most of the people on board are still alive.
We're standing, frozen in disbelief, right in front of the train. Thus far we have not even started to get out of the way.
Timely effective intervention in Liberia would have consisted of 150,000 - 200,000 US troops and additional medical personnel during the first week of September. Getting such a large force there by that effective date would have required at least seven weeks of time in transport, i.e, they'd have had to gotten their orders in June and started in full motion by the middle of July. Liberia's transportation infrastructure is that bad. You can't get fire hose quantities of water through a straw.
So the political decision to send them must have been made in June.
