A senior officer in the United Nations Command is urging caution about a declaration to end the Korean War, warning it could be a North Korean ploy to pull the South Korea-U.S. alliance apart.

Canadian Lieutenant-General Wayne Eyre is quoted as calling the prospective declaration a “slippery slope” in terms of the U.S. troop presence in South Korea.

In remarks at a Washington seminar, Eyre described the North Koreans as experts at "divide and conquer."

Abut 28-thousand-500 U.S. troops are based in South Korea to deter or defeat a repeat of North Korea's 1950 invasion or other provocations.

He said it needs to be questioned why North Korea is pushing so hard for an end-of-war declaration.

While noting that the recent climate of negotiations offered hope for a lasting peace, he suggested that a war-ending declaration would lead the public to question seriously the need for a continued U.S. troop presence on the peninsula.
