Frankly I'm worried about this one. Here are some facts as I see them:
The president of Iran is not nuts, but by western standards he might as well be. He seems determined to advance his brand of Islamic revolution to the exclusion of all other ways of life.
Islam, in its most fundamental form doesn’t tolerate dissent from within. And the Iranian President is playing to a hardened audience who may demand that the Iranians push the confrontation.
He has promised on numerous occasions, aware that the western press is taking notes, that he plans to remove Israel from the world.
Several experts believe that international isolation of Iran will not be effective because some nations will buckle under the energy demands of their citizens, and because Iran is not nearly dependent on the outside world as it is on them.
Iran has as many brilliant people they need to make a weaponized nuke that could ride atop a surface to surface missile.
Iran has removed the UN nuclear Inspectors from access to KNOWN nuclear facilities.
Iran very likely has the "plans" for a weaponized nuclear warhead that likely came from the helpful Pakistani Nuclear Scientist/proliferator of nuke designs.
Iran has a good surface to surface missile that is more than capable of hitting Southern Europe.
Israel has a right to exist.
I believe that a democratic and secular Iran with a moderate supply of nuclear weapons would not be considered the major threat that an Islamic Revolutionary Iran would be with even one or two nuclear weapons.
Israel is being regularly threatened verbally and actually threatened by terrorists funded by a nation that has funded Islamic terrorism for decades.
Israel may not have the conventional capability to make a decisive conventional pre-emptive strike.
US forces could essentially surround Iran by basing assets in Saudi Arabia, Diego Garcia, UAE, Iraq, Afghanistan, Pakistan, Uzbekistan, and Turkey and launch a massive strike using short-range fighters, bombers, naval assets, US-based B2 bombers, cruise missiles, as well as surface to surface missiles.
Israel would have to push their conventional strike capabilties along way and over some potentially hostile territory to just damage the Iranian program.
Israel has the capability to make a devastating preemptive nuclear strike against Iran and remove its nuclear facilities as well as the current Iranian government.
Israel may not be as concerned about the **** hitting the fan after a conventional and nuclear strike against Iran as the rest of the world thinks it is.
Many nations may ask the US to conventionally strike Iran in preference to the Israelis doing the dirty work.
Many national leaders who have derided the US and President Bush for Iraq will quietly pledge their acquiescence to a massive US/British strike.
Small yield nuclear weapons may be required by both the US and Israel to effectively take out some of the more hardened Iranian facilities.
Both the US and Israel are working on their war plans.
If the Iranian program is destroyed there will be even greater pressure to remove the nuclear capability of Pakistan. They own the only other "Islamic" bomb.
We can count on North Korea to go a little nuts when this crisis heats up.
Israel will not wait too much longer.
Al Queda may time one of their strikes in the US with the planned Iranian strike on Tel Aviv.
Iran could give Al Queda a nuke.
Like I said, I'm a bit worried.
