Countries are sending troops to halp with law and order as we speak.
Problem with using paratroops are that they are by definition "light infantry" themselves with limited supplies and no one knows how long the Airfields are going to be closed.
Worst case scenario is that you put troops into an area and donīt know if you can resupply them much less supply them enough so they can help the locals at all.
The thought is relevant I agree, but it is something that will have to be planned extensively.
Not enough fuel to fly the aid flights out amongst other problems.
"We are the pilgrims, Master
We shall go always a little further,
it may be beyond the last blue mountain barred with snow,
Across that angry or glimmering sea..."
