so it cannot manufacture the nuclear weapons

this is because it has to lead by example and also because if it did it would receive international sanctions like the ones being placed on North Korea. This is because after years of having a secret nuclear weapon manufacture program. The country has finally come out and said it out loud. It has also refused to cooperate with UN and USA; currently it is viewed as a dangerous country. The political and education sectors of the country will be drastically affected by these heavy sanctions.
