Obama reminds North Korea of U.S. 'military might'

SEOUL (Reuters) - President Barack Obama said on Saturday the United States did not use its military might to "impose things" on others, but that it would use that might if necessary to defend South Korea from any attack by the reclusive North.

The North warned last month it would not rule out a "new form" of atomic test after the U.N. Security Council condemned Pyongyang's launch of a mid-range ballistic missile into the sea east of the Korean peninsula.
