No. It doesnt mean God condones it.
Its a prophetic warning as to what the Medes are going to do to the Babylonians. There are similar passages where God warns the Isrealites that the Babylonians will come against them and carry out atrocities... and likewise there are other warnings to other nations about what will befall them at the hands of their enemies. And the reason why God allows such things to happen is because he will not protect the wicked from the wicked. Those who live by the sword will die by the sword for that is justice.
In all this, God implores mankind to turn away from human rulership because of the way man dominates and destroys. God never condones mans atrocities... he wants peace and he wants people to put down their weapons and love one another.
Eccl 8:9 All this I have seen, and there was an applying of my heart to every work that has been done under the sun, [during] the time that man has dominated man to his injury.
Micah 7:3 Their hands are expert at doing what is bad; The prince is making demands, The judge asks for a reward, The prominent one makes known his desires, And they work it out together
When anyone acts in wicked ways, God is far from that person as the prophet Isaiah says:
Isaiah 59:2 No, but the very errors of YOU people have become the things causing division between YOU and YOUR God, and YOUR own sins have caused the concealing of [his] face from YOU to keep from hearing. 3 For YOUR own palms have become polluted with blood, and YOUR fingers with error. YOUR own lips have spoken falsehood. YOUR own tongue kept muttering sheer unrighteousness. 4 There is no one calling out in righteousness, and no one at all has gone to court in faithfulness. There has been a trusting in unreality, and a speaking of worthlessness. There has been a conceiving of trouble, and a bringing of what is hurtful to birth.
God is not blessing the wars of men. He is not with those who murder and plunder. If anyone wants to know God, they must surrender to peace and righteousness first...only then will God allow himself to be found by them,.
