"US military attacks on North Korea depend on South Korea's attitude toward the alliance and the level of Pyongyang's provocations," Lee Choon-geun, a senior analyst at the Korea Institute for Maritime Strategy, said in the seminar.

North Korea has escalated tensions on the Korean Peninsula by conducting two nuclear tests and more than 20 missile tests last year. 

Despite such capabilities, many in Seoul want to avoid resolving the current standoff with the use of force, because of fear it can potentially lead to a military clash.

They said to prevent Washington from striking the North, South Korea needs to show it is firmly committed to the alliance and the goal of denuclearization.

Echoing the need to maintain calm, Song Won-geun, vice president of the Korea Economic Research Institute, a think tank under the South Korean business lobby FKI, to avoid any unintended military conflict between Washington and Pyongyang, the next government will need to pay close attention to ties with Washington.

"Close ties with the US should take precedence over all else," he claimed.

South Korea, meanwhile, faces tough times ahead since it agreed last July with the US to install the Terminal High Altitude Area Defense system here by the end of 2017 to counter threats from Pyongyang.

Its biggest trading partner China has explicitly opposed the anti-missile system's installation, arguing it could be used against it.

Last month, Beijing banned the sales of group travel packages to South Korea as part of its retaliation against the allies' ongoing process to complete the installation within this year.

Local campaigns against South Korean products in China also put a dent on South Korean businesses last month.   

Still, experts here said the North won't likely cross the Trump government's "implicit red line" that could trigger a decisive action by the US military. (Yonhap)
