Latest in the North Korea-US war of words
The report came after US Defense Secretary James Mattis noted that the US military would defend the country "from any attack, at any time and from any quarter". He further reassured Guam residents by vowing to "take it out" if North Korea acts out.
What do we know about the Guam plan?
According to the report which appeared in the state news agency, KCNA the country's strategic forces are prepared to "envelop Guam with fire".
It is merely waiting on orders to do this.
The report further noted that Kim Jong-un would watch US behavior before arriving at a decision.
Can this be taken to mean that North Korea may de-escalate if the US exhibits composure?

What context is this happening in?
North tested an Inter-continental Ballistic Missile last month. Kim Jong-un noted that the ICBM would bring the entire US within striking range.
In response, Trump threatened North with "fire and fury".
The UN permanent five also slapped fresh sanctions on North.
Last week, North Korea's military said it is considering launching missiles on Guam, a US base in the Pacific housing American strategic bombers.
Nuclear Weapons and North Korea
North Korea has run an ambitious nuclear program since the 1950s, although it performs poorly under several socio-economic indicators. Having conducted five tests between 2006-2016, the leadership's spontaneous behaviour, along with its threatening tone aimed at those including the US, create an atmosphere of insecurity.
Could American bombers push North Korea over the line?
North says it was compelled towards formulating an attack plan for Guam.
It feels threatened by American B-1B bombers, stationed in Guam, constantly flying above the Korean Peninsula, especially during heightened tension.
These bombers may just give North an opportunity to test out their Hwasong-12 intermediate-range missiles.
Conversely, if they stay on ground, Pyongyang can claim a victory over US.
A tricky situation?
Endless possibilities, whole lot of unpredictability: What does this mean?
The latest report may merely be looked at as more threatening rhetoric.
Making the decision to launch a strike conditional on US actions can further be seen as indicative of North Korea's willingness to de-escalate.
Analysts also note that North Korea may be creating a diversion to buy itself more time and prepare for an attack.
To conclude, with North Korea, you'll never know.
