If you have all relevant info about the current state, you can predict a close future state.

Weather prediction, for example, is more accurate tomorrow than a week from now, etc.

Humans are much less chaotic than the weather.

Also they are idiots, and tell other people what their plans and goals are (Agenda 2030).

If you had connections/spys, knew the enemy's whole network and hierarchy, and collected all the data you needed about current events, it would be easy to plan future events.
