Pretty screwed up situation - but what are the options here?

a) Airstrike by Israel
This would probably mean that we can kiss any hope of peace in the Middle East goodbye for the next decades. In the worst case this could lead to an open war in the region.

b) Airstrike by the US
Best way to cement the power of the current rulers in Iran. Who knows what that might mean for the situation in Iraq (nothing good I would guess).

In both cases a) and b) expect new recruits flocking to AQ.

Also it is very likely that both options only postpone the inevitable. If Iran has the know-how to make nuclear weapons they will continue to pursue them. The next target will be less obvious.
Any airstrikes will also show other countries that you better try to get your hands on nukes (preferrably without anybody noticing before it's to late) - after all North Korea seems to be in a pretty secure position with the threat of possibly existing nukes.

c) Keep on negotiating/do nothing
Most likely this will lead to Iran having nukes in the end. Not a situation I am personally looking forward to. Unfortunately and realistically we will probably have to get used to the idea of states we rather would not like to see having access to nukes getting their hands on them at some point (this djinni was out of the bottle the moment the first nukes were developed )

d) Embargo on Iran
Might help for a while, but in the end if Iran really wants nukes they will get them sooner or later - and an embargo might actually even increase their determination to get nukes.


In the end we will most likels see either an Iran with nukes or an awful lot of people will pay a very high price for preventing Iran from getting nukes.

I would probably go for option d) and hope for the best, but quite frankly, I do not like any of these options...
