You have begun a war with Azmenistan. You succeed in destroying much of the critical infrastructure of Azmenistan's nuclear program, but at a tremendously high cost.
Azmenistan responds with a massive bombing campaign of your capital city, destroying government buildings and killing thousands of civilians. A massive flow of refugees from your state and Azmenistan into Brezistan threatens to destabilize Brezistan (contagion), destroying your relationship with Brezistan.
To make matters worse, since you invaded Azmenistan, the international community views you as the aggressor. Your invasion garners no international support and your recovery effort will receive little international aid.
You have ended Azmenistan's nuclear program, at least for the time being, but at a tremendous cost to both states.
