Really? Then why would Netanyahu say you don’t need centrifuges - unless you want to have a bomb?
Why on earth would he say that ..??
Because you could pay someone else to enrich your fuel, using a centrifuge or a gaseous diffusion method (which is more expensive).
This may help you understand the issue.
In 2007, 72 percent of all enrichment was done by centrifuge plants and only 28 by gaseous diffusion. By 2017 centrifuges are projected to account for 96 percent of all uranium enrichment activity .
Current centrifuge facilities have been built ostensibly to enrich uranium for nuclear reactors. Centrifuges present a proliferation danger because precisely the same machines that produce low enriched uranium fuel for a nuclear reactor can produce highly enriched uranium suitable for nuclear weapons. Even a modest centrifuge plant, one sized to fuel a single nuclear power plant, can produce enough HEU for about twenty bombs in a year. The difference between a military and a civilian enrichment plant is just how the machines are piped together in cascades. This means that a fuel plant could quickly be converted into a weapon plant. Moreover, if the starting material for a bomb program were not natural uranium, but fuel-grade uranium that has been stockpiled, then the time to further enrich the uranium to bomb-grade would be reduced by more than 65 percent.
