The analysis of where we stand is correct, but the conclusion that the US negotiate with Iran doesn’t follow. Negotiate about what? The leaders of Iran are Islamofascist non-rational state actors.
Two ideas I have read:
1. US or Israel to completely destroy one facility, as an example to Iran of what will happen.
2. NATO or coalition to stop all refined gas imports to Iran, until they stop nuclear program.
I’m not sure that the WW1 analogy holds only because the disparity of strength between the antagonists. Iran is way outmatched by almost any measure you care to use. I’m not saying that Iran couldn’t do some considerable damage. Rocketing US bases in Iraq; doing the same to Saudi oil fields, dropping a Shahab onto Tel Aviv; closing the Strait of Hormuz — all are real possibilities. I just don’t think that they could sustain the military effort for long.
