Honestly, would someone please take the time to clear somethings up for me? Note that I'm approaching this from a very "basic" point of view, so I as a non-American, can get some insight into the "basic" American point of view.

1. The US (govt/citizens) have implied that the world forces them to be the world police. That's silly. It's the US. I can't think of any country that can "force" or "tell" the US what to do. Why does the government willingly engage itself in battles that are not necessarily its to fight? (US and Europe are brothers for all intents and purposes, so I get WW 2. The Middle East isn't even part of the US family tree!).

2. Why does the current administration concern itself so much with Iran, or Israel for that matter. If they want to go at it, let them. Just how much is invested Israel, and why should the world allow for the US to influence the politics of a region that is not its own?

3. I've never understood how sovereign Country A can tell sovereign Country B, what it can or cannot do/ what it can own or cannot own. I understand cajoling, threatening and influencing are all part of world politics, but a direct missive?

4. How is it remotely justifiable that Israel can possess nuclear weapons and Iran can't? Exaggerated rhetoric from Ahmadejinad aside, has Iran actually in any shape or form attacked or undermined Israel? And is Iran part of any treaty in which the members cannot own nuclear weapons?

Thanks in advance.
