Virtually every word out of Pompeo mouth was a threat-either to the United Kingdom, to Washington's "strategic adversaries" Russian Federation and China, or to those countries it is actively preparing to attack, including Venezuela and Iran.
The U.K. may still be persuaded to bar China's Huawei Technologies from building the country's 5G network, Sen.
But US State Department spokeswoman Morgan Ortagus said Pompeo was postponing the trip "due to a need for the secretary to be in Washington" on Thursday.
Pompeo skipped his meetings in Berlin with Chancellor Angela Merkel and Foreign Minister Heiko Maas to press Iraqi leadership on the importance of guaranteeing Americans' safety and reining in Iranian-backed Shiite militias in the country.
British Culture Secretary Jeremy Wright said separately it was still possible that the roll-out of 5G networks in Britain could be delayed by a review into telecoms equipment, adding: "The primary intention of this process is to get the security of the network right".
Secretary of State Mike Pompeo made an unannounced, dead-of-night jaunt to Iraq on Tuesday, showing support for the country's government in the face as escalating tensions between the USA and Iran. It is very important we control the sensitive parts of 5G networks. Immediately prior to Pompeo's arrival in London, he cancelled a scheduled trip to Germany in order to visit Iraq.
White House says China has indicated it wants to make trade deal
China's Commerce Ministry confirmed that Liu, who leads the talks for Beijing, will visit the USA on Thursday and Friday. Major stock indexes in trade-reliant Asia continued to fall on Wednesday, tracking a slide on Wall Street.
"We look forward to rescheduling the secretary's visit at a time convenient for Greenland, Denmark and the United States", she said.
Asked about the decision to move the aircraft carrier and bomber task force to the region, Pompeo said the United States wanted to defend its interests from the Iranian threat and ensure it had the forces necessary to accomplish that goal.
The UK and the USA are also in conflict over Iran.
American allies are pushing back and asking Washington how it intends to handle the fact that some of the smaller USA telecom companies also use Huawei equipment in their current generation networks, Warner said.
"Should Iran cease to observe its nuclear commitments, there would of course be consequences", he said. China and Russian Federation also signed the accord and have vowed to remain part of the deal.
Iran on Wednesday said it would suspend some commitments under a 2015 nuclear accord rejected by Trump, frustrated that renewed United States sanctions have prevented the country from enjoying the economic fruits of compliance with the deal. Pompeo was asked his thoughts on UK Labour Leader Jeremy Corbyn's "endorsement" of Maduro, a reference to Corbyn's criticism of the USA for "outside interference" in Venezuela.
