The Iran Attack Plan - Anthony Cordesman, Wall Street Journal.
Iran's acknowledgment that it is developing a second uranium-enrichment facility does little to dispel the view that the regime is developing a weapons program. Israel must consider not just whether to proceed with a strike against Iran - but how.
... Iran has all of the technology and production and manufacturing capabilities needed for fission weapons. It has acquired the technology to make the explosives needed for a gun or implosion device, the triggering components, and the neutron initiator and reflectors. It has experimented with machine uranium and plutonium processing. It has put massive resources into a medium-range missile program that has the range payload to carry nuclear weapons and that makes no sense with conventional warheads. It has also worked on nuclear weapons designs for missile warheads. These capabilities are dispersed in many facilities in many cities and remote areas, and often into many buildings in each facility - each of which would have to be a target in an Israeli military strike.
It is far from certain that such action would be met with success. An Israeli strike on Iran would be far more challenging than the Israeli strike that destroyed Iraq's Osirak reactor in 1981. An effective Israeli nuclear strike may not be possible, yet a regional nuclear arms race is a game that Iran can start, but cannot possibly win. Anyone who meets regularly with senior Israeli officials, officers and experts knows that Israel is considering military options, but considering them carefully and with an understanding that they pose serious problems and risks.
One of the fundamental problems dogging Israel, especially concerning short-ranged fighters and fighter-bombers, is distance. Iran's potential targets are between 950 and 1,400 miles from Israel, the far margin of the ranges Israeli fighters can reach, even with aerial refueling. Israel would be hard-pressed to destroy all of Iran's best-known targets. What's more, Iran has had years in which to build up covert facilities, disperse elements of its nuclear and missile programs, and develop options for recovering from such an attack...
