The international community, and especially Brezistan, are angered and give up on you as a partner.
Azmenistan reaches the cusp of successfully producing a nuclear weapon, and you are blamed in the international community for allowing it to reach this point.
Most of your allies forsake you. While your relations with Azmenistan remain positive, you become an international pariah.
Your economy suffers dramatically, and you lose almost all influence internationally.
You are voted out of office in the next election and watch from the sidelines as Azmenistan becomes an ever-growing threat to state security and regional stability.
