I do not buy your implied suggestion that says those that allied with the US have gained any thing from that country. I do see not even one country that has really benefited. Once you become dependent on the US, she will start interfering in all your affairs.
Yes, nuclear issue is altogether a different issue, and I support it on its merit. But can we make the US adhere to all those that that country has promised in it, in future. That is a big question. She will surely invent some thing or other for defying any rule or treaty, if she found, at any time, any thing that does not suit her. It is for sure.
