I hope not as well, but it just seems inevitable.
I don't have trouble believing the plot was real, but I certainly don't believe its mere existence warrants military action. There has to be some consequence but I'm sure they will be limited to ineffective sanctions (Another reason not to believe the plot was a sham).
Again, assuming the plot was real (and I don't know why we shouldn't) it reveals an alarming degree of recklessness somewhere within the regime, and I'm not sure why they won't try it again.
Unless the decision makers are insane (and I don't believe they are) a nation doesn't take a chance like this unless they feel pretty certain that they can survive retaliation.
What would the consequences have been if the Saudi Ambassador had been blown up along with a dozen Americans in a DC restaurant? Hard to imagine invasion and all out war and so if military action was felt to be required, a couple of cruise missiles would likely have been fired at Qud headquarters.
The Iranian theocracy and the Qud Forces both can survive a pair of missiles.
Iran is probably counting on the US to prevent Israel from attacking its nuclear reactors, but they can't be certain we will. Some part of their accepted equation has to include limited bombing of their country by a foreign power. I imagine that the regime at least believes it can survive such an attack.
Bold actions taken with serious risk at stake and so I have to believe the expected payoff is pretty dramatic: Iranian control over the entire region; including its oil reserves.
I know that there are some deluded souls who actually believe Iran is developing nuclear capabilities as a source of energy alone, but I doubt that any of them occupy a seat of power in the Middle East.
From where does any message sent by the murder of the Saudi ambassador come from? Iran's purely defensive concern that it simply be left alone by a country (Saudi Arabia) that has shown no interest in military belligerence?
Iran is either a very paranoid, but essentially peaceful country, or they have plans for controlling the region. Pretty easy choice for me.
It's impossible for me to see a way that Iran achieves their expansionist goal without coming to actual blows with the US.
I would say within the next five years; perhaps in the early days of a new president's administration, and that it will involve Israel in some way (hardly have to climb out on a limb with that predication).
