In recent weeks Iran announced that it had begun work on enriching uranium to 20 percent -- just short of the level required to produce nuclear weapons -- as well as informing the International Atomic Energy Agency... that it was to resume work on producing uranium metal.

Both these developments represent a clear breach of the JCPOA. Under the agreement, Iran committed to keep uranium enrichment at 3.5 percent, the level required for civilian use, and signed up to a 15-year ban on "producing or acquiring plutonium or uranium metals or their alloys".

Iran's announcement that it was proceeding with the production of uranium metal has prompted a furious response from the foreign ministers of Britain, France and Germany, who, in a joint statement earlier this month, warned that there was "no credible civilian use" for the element, and that "The production of uranium metal has potentially grave military implications.

[W]hat makes anyone think Iran would honour a new deal any more than they honoured the old one? Why enter a new sham deal at all?

Not a week has passed since the inauguration of President Joe Biden -- whose son reportedly engaged in business deals with China worth $1.5 billion -- and the Chinese Communist Party, which illegally seized Hong Kong last summer, has already sent more than two dozen warplanes, including bombers, into Taiwan's airspace for two days in a row.

China also issued a new law permitting its "coastguards to launch pre-emptive strikes without prior warning" on any foreign ship that might enter disputed waters that China would like to consider its own.

Biden's team should not misinterpret any Chinese conciliatory rhetoric as being a sign of a less aggressive CCP effort to push US military assets out of the Western Pacific.

Xi, a stalwart of the "One China Policy," may still demand not words but actions, such as: a moratorium on Freedom of Navigation Operations (FONOPS) by US Navy vessels in the South China Sea, a cessation of US criticism of Chinese human rights violations, and a promise to reduce American VIP visits to Taiwan following President Trump's high-level contacts with Taipei.

China has clearly assessed Biden's capacity for bold leadership as highly improbable.

The Biden administration should not assume that Chinese objectives are negotiable. The CCP is committed to becoming the premier power in the world at the expense of US interests and is most likely willing to risk war to accomplish it.
