Why should the US be the only country that says who can own nukes ?
Why shouldn't everyone be a bully?
I don't think protecting your sovereignty is equivalent to being a bully. If you have no nukes, you can be conquered by anyone who does.
You are correct. They didn't start this. Someone else did. The problem with that logic is that we all end up with bullies protecting our sovereignty, to the point where we wonder what good it is anyway.
