PYONGYANG, North Korea — Scores of North Koreans of all ages planted trees as part of a forestation campaign — armed with shovels, not guns. In the evening, women in traditional dress danced in the plazas to celebrate the 20th anniversary of the late leader Kim Jong Il's appointment to a key defense post.
Despite more warnings from their leaders of impending nuclear war, people in the capital gave no sense of panic.
Chu Kang Jin, a Pyongyang resident, said everything is calm in the city.
"Everyone, including me, is determined to turn out as one to fight for national reunification ... if the enemies spark a war," he added, using nationalist rhetoric common among many North Koreans when speaking to the media.
The North's latest warning, issued by its Asia-Pacific Peace Committee, urged foreign companies and tourists to leave South Korea.
"The situation on the Korean Peninsula is inching close to a thermonuclear war due to the evermore undisguised hostile actions of the United States and the South Korean puppet warmongers and their moves for a war against" North Korea, the statement said Tuesday.
There was no sign of an exodus of foreign companies or tourists from South Korea.
White House spokesman Jay Carney called the statement "more unhelpful rhetoric."
"It is unhelpful, it is concerning, it is provocative," he said.
The warning appeared to be an attempt to scare foreigners into pressing their governments to pressure Washington and Seoul to act to avert a conflict.
Analysts see a direct attack on Seoul as extremely unlikely, and there are no overt signs that North Korea's army is readying for war, let alone a nuclear one.
North Korea has been girding for a showdown with the U.S. and South Korea, its wartime foes, for months. The Korean War ended in 1953 with an armistice, not a peace treaty, leaving the peninsula still technically at war.
In December, North Korea launched a satellite into space on a rocket that Washington and others called a cover for a long-range missile test. The North followed that with its third underground nuclear test in February, a step toward mastering the technology for mounting an atomic bomb on a missile.
Tightened U.N. sanctions that followed drew the ire of North Korea, which accused Washington and Seoul of leading the campaign against it. Annual U.S.-South Korean military drills south of the border have further incensed Pyongyang, which sees them as practice for an invasion.
Last week, North Korean leader Kim Jong Un enshrined the pursuit of nuclear weapons — which the North characterizes as a defense against the U.S. — as a national goal, along with improving the economy. North Korea also declared it would restart a mothballed nuclear complex.
Adm. Samuel Locklear, commander of U.S. Pacific Command, told the Senate Armed Services Committee in Washington on Tuesday that he concurred with an assessment by Sen. John McCain, R-Ariz., calling the tension between North Korea and the West the worst since the end of the Korean War.
"The continued advancement of the North's nuclear and missile programs, its conventional force posture, and its willingness to resort to asymmetric actions as a tool of coercive diplomacy creates an environment marked by the potential for miscalculation," Locklear told the panel.
