According to the New York Times, Gen. Vincent K. Brooks, the top U.S. general in South Korea, said that the only thing stopping war between U.S./South Korean joint forces and North Korea is "self restraint".
The country's state media claimed they had the power to now strike the American mainland with a nuclear warhead.
But while U.S. President Donald Trump appeared to be caught somewhat off guard by the launch, musing on Twitter over why North Korean leader Kim Jong Un doesn't have better things to do with his life, Kim and his regime have been clearly telegraphing their moves.
South Korean President Moon Jae In said "the situation was no longer sufficient to respond to the North's provocation by making statements", according to his office, while his defence ministersaid there was a high possibility of a sixth nuclear test by the North.
Missiles are being fired during a joint Korea-U.S. missile exercise on the east coast on Wednesday.
North Korea conducts about 90 percent of its trade through China, giving Beijing enormous sway over the reclusive government.
Yesterday ICBM launch, confirmed by US and South Korean officials, was a milestone in North Korea's efforts to develop long-range nuclear-armed missiles.
Donald Trump's initial response was to ask China to put a "heavy move" on North Korea, while the country's United Nations ambassador warned that the "possibility of a diplomatic solution" is narrowing.
"As we, along with others, have made clear, we will never accept a nuclear-armed North Korea", he said. "We will use them if we must, but we prefer not to have to go in that direction", she said. It would risk an uncontrolled escalation, including even a nuclear one. (We should) have talks about talks with no preconditions.
"It's the most hopeful option that we have, but it's also probably the least likely", he said.
The Trump administration has said it is open to diplomatic negotiations with North Korea, but only under the right conditions.
Restricting guest workers is one way the US and other countries could try to reduce North Korea's access to foreign currency.
Adding that the global community has spoken frequently against the "illegal and unsafe actions of the North Korean regime", Haley noted that for "many years, there have been numerous United Nations sanctions against North Korea - but they have been insufficient to get them to change their destructive course".
"China has always been firmly opposed to chaos and conflict on the Korean peninsula". "The president has directed us to not do that and to prepare a range of options, including a military option, which nobody wants to take".
Russian and Chinese diplomats used the U.N. Security Council meeting to push their joint proposal for a suspension of North Korean nuclear and missile testing in exchange for a suspension of US and South Korean military exercises.
A North Korean soldier, who was training to guard one of Kim's palaces, has fled the Hermit Kingdom for freedom. "Any agreement would be unsatisfying and prone to failure", he said.
