US President Donald Trump vowed to respond with "fire and fury", raising fears of a devastating regional conflict, and the UN Security Council scrambled to impose new punitive measures on the North.
During last year's drills, the North successfully test-fired for the first time a submarine-launched ballistic missile ruler Kim Jong Un then praised as the "success of all successes".
Trump has used Twitter to launch his own insults at North Korea and its leader, Kim Jong Un. "Hard to believe that South Korea. and Japan will put up with this much longer". "And maybe - probably not - but maybe something positive can come about", he said, but did not explain what kind of an agreement he was expecting to reach with North Korea. Trump's comments today came after Secretary of State Rex Tillerson said the North Korean regime has demonstrated some level of restraint in recent days, "that we've not seen in the past".
"I am pleased to see that the regime in Pyongyang has certainly demonstrated some level of restraint that we've not seen in the past", Tillerson told a press briefing on Tuesday, adding that the USA needed to see more restraint before allowing for meaningful dialogue to take place.
The Trump administration's rhetoric has been highly variable but Washington has said it would be open to dialogue if Pyongyang took steps to calm tensions.
It went on to urge the United States and its allies to "act with discretion if they want to evade the historic moment of death".

"It's not a missile test but it's still very disconcerting for people who look at the North Korean ballistic missile program", Duitsman.
"I don't think there's any accident about this, the shot clearly shows Pukguksong-3, this was the North Koreans showing us what we could possibly see soon", he said.
KCNA said the nosecones and engine jets were made of "carbon/carbon compound material", and that Kim "instructed the institute to produce more solid-fuel rocket engines and rocket warhead tips".
The video published by state media outlet Uriminzokkiri comes after the United States and South Korea yesterday began its annual war games military exercises.
US Secretary of State Rex Tillerson on Tuesday added momentum to tension reduction, praising the North for showing a "level of restraint" in not conducting nuclear or missile tests since new United Nations sanctions were imposed.
On Tuesday the US Treasury slapped sanctions on 16 Chinese and Russian individuals and companies, accusing them of supporting North Korea's weapons programmes and attempting to evade US sanctions.
