On the subject of national judgments, you can find a lot of Puritan literature which I cited in this thread:

Special Providences

In particular, I would recommend:

Patrick Gillespie, Rulers Sins, The causes of National judgments, or a Sermon Preached at the Fast, upon the 26th Day of December 1650
Daniel Williams, What repentence of National Sins doth God require, as ever we expect National Mercies?
John Collins, How the religious of a nation are the strength of it
Thomas Vincent, God's Terrible Voice in the City
Matthew Henry, A Memorial of the Fire of the Lord
Stephen Charnock, A Discourse Upon the Fifth of November or On God as a Deliverer
Obadiah Sedgwick, Providence Practically Handled
