To Davis, the missile testing itself, and how it was done, demonstrated a potential threat to the U.S.: "This act demonstrates that North Korea poses a threat to the United States and our allies and we remain prepared to defend ourselves and our allies and to use the full range of capabilities at our disposal". "And meanwhile, North Korea keeps getting better and better".
Schiller noted the example of Russia's latest submarine-launched missile, the Bulava.
North Korean leader Kim Jong-Un reportedly oversaw the launch and said the projectile was "as handsome as a good-looking boy".
"There is an argument to be made that everything has changed and nothing has changed", said Jim Walsh, senior research associate at the Massachusetts Institute of Technology Security Studies Program, adding that the test had demonstrated new North Korean capabilities and taken the U.S. across a psychological and political threshold.
She added: "One of our capabilities lies with our considerable military forces". The Hwasong 14 isn't believed to be accurate enough to attack small targets despite Pyongyang's claims otherwise, but that isn't a major concern if it is meant to be a threat to large population areas, such as cities on the US West Coast.
The speech, along with his meeting with Duda and a session with other Eastern European leaders on energy infrastructure investment, kicks off Trump's second trip overseas as president, a critically important trip that will later see Trump discuss trade, climate and migration at the G20 meeting in Germany.
President Trump is clearly frustrated with what he perceives as China's failure to rein in its trading partner.
She also warned that Washington is prepared to cut off trade with countries trading with North Korea in violation of United Nations resolutions.
The bar for having an operational ICBM is also higher for the North if the United States is its target. That's not going to happen. Although increasingly stringent UN sanctions against the North Korean regime and its leaders have not worked in the past to change the rogue regime's behavior, Secretary Tillerson is looking for even "stronger measures" from the UN Security Council.
Russian Federation at one point referred to the missile that North Korea just tested as "mid-range", which drew a sharp rebuke from Ambassador Haley.
"If you choose not to we will go our own path", Haley said. She flagged that she will table a new resolution in the coming days outlining a raft of new sanctions, affecting air and sea links, currency transactions and the export of oil to North Korea.
Following North Korea's July 4 launch of its first intercontinental ballistic missile, deemed by U.S. officials to be capable of reaching Alaska, U.S. officials invoked direct threats of military action as they tried to marshal coordinated global action.
Since the collapse of the Soviet Union in 1991, the key objective of American imperialism has been to prevent the emergence of any single power or group of powers that could challenge U.S. dominance around the world.

"It's a shame they're behaving this way - they're behaving in a very, very unsafe manner and something will have to be done about it", Trump said in a news conference Thursday with Polish President Andrzej Duda.
Britain's foreign minister Boris Johnson described North Korea's test launching of nuclear weapons as "reckless" on Thursday, saying it was important that China increases pressure on Pyongyang.
Since President Ronald Reagan's administration in the 1980s, the United States government has spent more than $200 billion to develop and field a range of ballistic missile defense systems ranging from satellite detection to the sea-based Aegis system, according to the Congressional Research Service.
Worry also spread in Washington and at the United Nations, where the United States, Japan and South Korea requested an emergency U.N. Security Council session Wednesday.
He said Moscow also objected to the presence of some military forces in North-East Asia under the pretext of countering Pyongyang's military programmes. China's efforts to influence its neighbor have frequently been rebuffed, even after Beijing cut off coal imports from North Korea earlier in February.
Humanitarian efforts must be depoliticised, he added, underlining that sanctions would not resolve the issues.
Restricting guest workers is one way the US and other countries could try to reduce North Korea's access to foreign currency.
