Given a week+ transit time, not very.
The slow transit time would slow the action. It might not change the character of it. The little I understand on complexity theory says:
1) a complex system can have a critical state in which some element has a multiplying effect cascade action.
2) because of this the odds of a maximum possible result go up in an exponential way with the relative size of the system. It has nothing to do with the size of the triggering event, or the speed of the interconnection.
A fission bomb explosion and the collapse of the Roman empire are two examples of complex systems.
I can see the delay time producing a slower action.
In economics, an example would be:
for a simplex system, the systemic counter party risk of failure is calculated on a net (those who cover the risk less those who need to cover it) basis, but with a complex system, the systemic risk is additive. (those who cover it plus those who need to cover it.) I can't do the math myself, but this is my understanding. Part of the reason for unpredictable timing is that it isn't obvious when a complex system changes from non-critical to critical.
A complex system follows power law distribution, rather than normal distribution of results, producing a "fat tail" pattern.
All of which says "we didn't expect playing with just one match would start such a large forest fire."
The key to stopping or preventing a complex system result is either 1) reducing the number of independent agents (spray that increasingly large pile of sand with a binding agent to reduce the chance of the sand sliding) which in a society means more rigid control, or 2) reducing the strength of interconnections (such as having a power grid of many micro-grids which disconnect when under strain.)
When we moved here, this town had a backup diesel generating station, which has since been taken down.
There are a few small backups (for the old folks home, etc.) but for the town, the situation has become less stable.
Looking at the ebola situation, resolution is likely to depend on which complex system is faster: the spread of the disease, or putting into effect by enough people of known methods of reducing that spread. (Basically, this is quarantine.) The problem is the need to both spread the knowledge and ACT on it consistently. I understand the patient in Spain absently minded brushed the cheek with a glove that had not been sterilized by washing with bleach.
