North Korea vehemently denied the allegation and said it will "take revenge" on the United States for saying it is developing biological weapons. The report was even verified in President Donald Trump's new national security strategy, which stated North Korea was "pursuing chemical and biological weapons which could also be delivered by missile".
"North Korea-a country that starves its own people-has spent hundreds of millions of dollars on nuclear, chemical, and biological weapons that could threaten our homeland", the document states. It brags the rocket can hit the mainland US. "While I think the North Koreans believe we have biological weapons and would like the ability to deter us by responding in kind to any sort of attack, it's just not a very practical category of weapon for intercontinental delivery". Let's hope we never find out exactly how long.
North Korea sees the regular joint exercises as preparation for war.
Mr Johnson's dire warning - revealed today by Sun columnist James Forsyth - echoes similar doomsday predictions from military top brass.

More recently, there was several instances of bioterrorism in the United States in 2001, whereby letters containing anthrax spores were sent to several news media outlets and USA senators Tom Daschle of South Dakota and Patrick Leahy of Vermont. Three weeks later, another two letters were sent to USA senators.
A wave of attacks occurred in the United States in late 2001 with the spores placed in envelopes which killed five people.
Anthrax, once in the environment, can be spread about the population when it comes into contact with clothes or shoes.
Anthrax contaminates the body when spores enter it, multiplying and spreading an illness that could be fatal.
North Korea vehemently denied that it was developing biological weapons and said it would take revenge on the USA for suggesting in a report that the East Asian country was "pursuing chemical and biological weapons which could also be delivered by missile".
It is not only Trump railing against the North Korean despot.
And he added that an accidental clash was "extremely great". Overseas experts, however, are divided over whether or not North Korea has succeeded in minituarizing its fissile materials down to warhead size. However, until there is more solid information, Washington should take care not to overreact.
