Does the west have the guts to stop Iran????

Certainly not the Europeans, who just love to talk..but have the Americans also lost their nerve?

Every day that goes by allows Iran to increase the threat it poses, and the viability of the military option steadily declines over time. There are a number of reasons why this is so.

First, while the European-led negotiations proceed, Iran continues both to convert uranium from a solid (uranium oxide, U3O8, also called yellowcake) to a gas (uranium hexafluoride, UF6) at its uranium conversion facility at Isfahan. Although it is a purely chemical procedure, conversion is technologically complex and poses health and safety risks.

As Isfahan's continuing operations increase both Iran's UF6 inventory and its technical expertise, however, the impact of destroying the facility diminishes. Iran is building a stockpile of UF6 that it can subsequently enrich even while it reconstructs Isfahan after an attack, or builds a new conversion facility elsewhere.

Second, delay permits Iran to increase its stock of low-enriched uranium (LEU) -- that is, UF6 gas in which the U235 isotope concentration (the form of uranium critical to nuclear reactions either in reactors or weapons) is raised from its natural level of 0.7% to between 3% and 5%.

As its LEU stockpile increases, so too does Tehran's capacity to take the next step, and enrich it to weapons-grade concentrations of over 90% U235 (highly-enriched uranium, or HEU). Some unfamiliar with nuclear matters characterize the difference in LEU-HEU concentration levels as huge. The truth is far different. Enriching natural uranium by centrifuges to LEU consumes approximately 70% of the work and time required to enrich it to HEU.
