U.S. President Donald Trump said on Monday he had paused a planned attack against Iran after Tehran sent a peace proposal to Washington, and that there was now a "very good chance" of reaching a deal limiting Iran's nuclear program. After Iran sent the U.S. a new peace proposal, Trump said he had instructed the U.S. military that "we will NOT be doing the scheduled attack of Iran tomorrow, but have further instructed them to be prepared to go forward with a full, large scale assault of Iran, on a moment’s notice, in the event that an acceptable Deal is not reached."
Experts Confirm the Fast16 Malware Was Sabotaging Nuclear Weapons Tests, Likely in Iran
Kim Zetter | Zero Day
Researchers have confirmed that a remarkable piece of malware discovered years ago but analyzed only recently was designed to subvert nuclear weapons testing simulations with the aim of undermining those tests and slowing the progress of a nuclear program. The new report, from researchers at the security firm Symantec, confirms what has only previously been speculated about the code by the company that first discovered it — SentinelOne. The malicious code, known as Fast16, was designed to subvert at least two specialized software programs that were commonly used for simulating weapons explosions at the time the code was active in 2005.

Trump says 20-year nuclear programme suspension by Iran would be enough
Robert Greenall | BBC
US President Donald Trump has said he would accept a 20-year suspension by Iran of its nuclear programme, in what appears to be confirmation of a shift in position away from a demand for a total end to it. Trump said it had to be a "real 20 years". Previously he has called on Iran to permanently cease enriching uranium - a stage in making a weapon - and to be prevented from ever acquiring nuclear weapons.
US, China to work on denuclearizing North Korea: White House
Anton Sokolin | NK News
The leaders of the U.S. and China have agreed to jointly work toward the denuclearization of North Korea, according to the White House, following President Donald Trump’s recent visit to Beijing. “President [Donald] Trump and President Xi [Jinping] confirmed their shared goal to denuclearize North Korea,” the White House said Sunday in a fact sheet after Trump returned from his two-day trip to China. The text also contained a statement about Iran, stating that Trump and Xi “agreed that Iran cannot have a nuclear weapon.” The White House’s statement contrasted sharply with Beijing’s official post-summit readouts. The Chinese foreign ministry briefly mentioned the two leaders talked about the Korean Peninsula in broad terms, among other concerns in Ukraine and the Middle East.
