Oh, I agree that they are going to get worse if we do nothing. They are also going to get worse if we do something. All things being equal, I would really prefer we do something; let me be very clear on that. But if you think what we are in now is full scale jihad, you are sadly mistaken. But ultimately, their goal is to drag us into a state of total war with the muslim world. That will be full scale jyhad, and thankfully, we are not quite there yet. But Iran could dangerously up the stakes. They do have chemical and biological weapons. And they would give them to terrorists given half an excuse.
That being said, they cannot be allowed to have nuclear weapons. But let's not fool ourselves. Things are going to get a hell of a lot worse over the next few years, even decades, barring some sort of near-miracle.
Thanks for the clarification (I wasn't sure where you were coming from). Iran seems to be doing everything possible to start a War with the US right now, which makes me wonder if they don't have assurances from Russia that they will not 'intervene' to help the US or worse....that they will help Iran to defeat the US.
