Can someone please explain to me the problem with Iran having nuclear missiles? (I know that this is slightly off-topic).

There are three main problems.....

1) There government is fairly unstable, at times it was suspected the young people would overthrow the old guard, and there is still a chance of that happening to Iran going to a more democratic type of process as it goes on and on, as there are still lots of protests.

As such, during a revolution.... where the state is fighting for it's lives.... who's watching the missles?   This is a problem even with russia today, though thankfully do to the USSR collapse being handled diplomatically rather then just falling apart, a lot of the problems were handled ok.

It's the same reason it's a huge problem that Pakistan has nuclear weapons.  Only thing is... once someone has nuclear weapons, you can't take them away.

2) Iranian rhetoric seems to indicate that they don't understand the meaning... or don't care at least about "Mutual Destruction."

During the cold war, The United States and Russia came close to nuking each other many times.  With less stabe and responsible leaders, the chances of this happening rises exponentially.  It's possible they may shoot a couple of nuclear missles at Israel in hopes to wipe it out before retaliation... expecting the rest of the world to sit back and not do anything.  Which is possible.  

It's basically letting someone have a loaded gun who saying "I don't care if i get shot so long as I can shoot that guy.

3) Or just use nuclear weapons as a threat to other nations like Europe and the United States while invading other Middle Eastern Countires.... as Iran I believe still supports the "Greater Iran" notion that it's land should encompass "Greater Iran".

well , I know why Iran shouldn't have one but I don't know why "OTHERS" can have them although they killed and did horrible stuff lately..............

Because once someone gets Nuclear Weapons you can't take them away. 

Because they have nuclear weapons.

Letting everyone have nuclear weapons is like creating the political situation before WW1 again.... except instead of a war, it would be armmageddon.

To prevent ANY country from developing nuclear weapons be it Iran or Sweeden is a good idea.

Though espiecially Iran.

I dunno, those Swedish have been pretty dubious, recently.

Maybe they secretly dream about the days when Swiss mercenaries were the most feared soldiers on Europeon battlefields.

Aren't the Swiss from Switzerland?

Yes they are.  Switzerland was who i meant at first actually.

What with the being nuetral thing.

Don't know why I put Sweeden.

Makes sense. With America now more willing to engage, it would be politically more prudent for Amadinejad to at least appear that he's willing to negotiate. Iran is not so willing to antagonize the world, they just want to posture

They shouldn't be taken lightly, of course, but they can still be negotiated with. Progress with Israel will probably help progress with Iran, as will progress in Iraq. But as Iraq moves forward, Israel is probably going to take a step back. A small one if Livni comes out on top, a larger one if Netanyahu does.

Yeah, the Netanyahu thing will cause a big problem.

To me it seems inevitable he'll come out on top since it seems like the Nationalist party is much more in line with the Likud.

He doesn't seem like another Ariel Sharon willing to suddenly say "Screw you" to his party.  In fact he seems the opposite.
