Perhaps the US would like to threaten military strikes against another nuclear state:
Brazil has joined the select group of countries with the capability of enriching uranium as a means of generating energy.
A new centrifuge facility was formally opened on Friday at the Resende nuclear plant in the state of Rio de Janeiro.
The Brazilian government says its technology is some of the most advanced in the world.
The official opening follows lengthy negotiations with the United Nations nuclear watchdog, the IAEA.
Brazil has some of the largest reserves of uranium in the world but until now the ore has had to be shipped abroad for enrichment – the process which produces nuclear fuel.
It’s so much easier targeting Iran (unless, of course, you’re Britain’s former Foreign Secretary, dismissed for daring to scoff at suggestions the US would use nukes against the Islamic state.)
