Hmm. That was dizzying to follow but I think I got the gist of it.
This is one of the unfortunate realities of the modern day that we have to live with and cannot seem to avoid.
Having nuclear weapons while simultaneously saying another one cannot have nuclear weapons is one of the uncomfortable, but unavoidable things.
Iran is a nation that has been actively trying to hurt and kill Americans and westerners for many years, with varying degrees of success, too.
If a crazy man comes into the park where my children are playing and threatens, and hurts them repeatedly, if I have a gun, I'm going to stop that person, and it won't bother me at all to be 'hypocritical' and say I can have a gun and you can't. In that moment I'll be unconcerned what people's opinions are, I'll just know this dangerous, murderous person [Iran's schoolchildren chant Death to America] will not be allowed to have a gun under my watch.
The most powerful people will end up deciding who can or cannot have nuclear weapons. Let's hope that countries which generally want people to be free and prosperous (not those which crave the termination or genocide of their neighbors) are the ones who stay in the 'powerful' group.
