Under attack

In 2 Chronicles 32 Hezekiah feels a threat from Sennacherib. His course of action:
1) Make his area look less appealing (they go and stop up the water supplies)
2) Fortify his defences
3) Tells his military guys to remember that the Lord helps us and fights our battles.
Then Sennacherib lays seige to the area, an outright threat. He delivers a campaign of intimidation and mocking of God. It is interesting that he begins with a mental terrorist campaign instead of a physical one.
Hezekiah's new course of action:
1) Pray
Hezekiah did everything he could do to prepare. Then he prays and God delivered his country/area.
