North Korea touched off another underground nuclear test today, large enough to register as an earthquake on foreign seismographs.

The hermit kingdom confirmed the shot in a statement shortly after, saying this device was a lighter, miniaturized version of its previous ones. South Korean officials said the explosion was far larger than the tests in 2009 and 2006.

And then President Obama replied with — wait for it — another prepared statement calling the dictatorship’s latest nuclear test “a highly provocative act.” He also said he’d remain “vigilant.” And Obama warned that he’s going to consult even more with allies. Obama even promised additional “close coordination with allies and partners.”

Obviously, President Obama means business again. Still. The administration said similar things after North Korea’s long-range missile test in December.

To top off international reaction, the United Nations decided to convene today to talk some more.

Obama has been warning North Korea regularly while trying unsuccessfully to engage its Looney Tunes regime. Much as he has with Iran, which also is working on its own nuclear weapons program and has shown itself equally oblivious to the Democrat’s hollow warnings and economic sanctions.

As a sign of Obama’s resolve or something, his administration has recently withdrawn one of the two U.S. carriers stationed off Iran in the Persian Gulf.

Obama is scheduled to present his fifth State of the Union address to a joint session of Congress this evening and is expected to call for a further reduction of U.S. nuclear weapons from 1,700 to possibly 1,000.
