I wrote a little while ago that "If I lived in Iran I'd possibly think that they needed nukes...", one of the main arguments for this was
"Iran is basically encircled by either the US's allies, countries the US are currently occupying/have a strong military force, or nuclear armed countries."
Yesterday, one of my friends posted the following picture on Facebook, if this is correct then I think it emphasises the point even more.
So now remind me again - which country is the more aggressive toward the other? If you put someone in a corner, do you not expect them to try and fight back?
