Nahum 2: the destruction of Nineveh comes

Nineveh is strong (on top of the world) according to chapter 1:

12
And God has something to say about all this:
    “Even though you’re on top of the world,
With all the applause and all the votes,
    you’ll be mowed down flat.


but in chapter 2, we read:

13
“Assyria, I’m your enemy,”
    says God-of-the-Angel-Armies.
“I’ll torch your chariots. They’ll go up in smoke.
    ‘Lion Country’ will be strewn with carcasses.
The war business is over—you’re out of work:
    You’ll have no more wars to report,
No more victories to announce.
    You’re out of war work forever.”

Nahum wrote it when Nineveh was strong and dominating Judah, so his message was similar to someone in Jesus times saying that Rome would fall. Certainly, a message that could rise problems to Nahum
