On televisions last Tuesday, it was declared that Liberal politician Moon Jae-in decisively won South Korea’s presidential election. It was a great news that his victory will eventually end a decade of conservative rule.

“I will make a just, united country, I will be a president who also serves all the people who did not support me,” he told the crowd.

Moon was ahead of 40% from the gathered 80% of the votes counted at 1705 GMT according to the National Election Commission. His challenger, the conservative candidate Hong Joon-pyo, was next with 25.5 percent followed by centrist candidate Ahn Cheol-soo with 21.4 percent.

The White House congratulated Moon on his election win, saying it looked forward to working with him to strengthen the longstanding U.S.-South Korea alliance.

A U.S. official said that Moon’s victory will strengthen ties with Washington. The official who speaks under anonymity said that Moon may moderate his stand on installation of the U.S. Terminal High Altitude Area Defense (THAAD) anti-missile system once he is in office and is not expected to significantly change the alliance.

On Wednesday, Moon is expected to be sworn in for a five-year term. He doesn’t want an extravagant ceremony for him but instead, he wants to immediately start working. He will immediately name that prime minister to be approved by the parliament and as well as the main cabinet posts, including national security and finance ministers.

The newly elected president is approved of dialogues with North Korea to ease tension over its accelerating nuclear and missile program. He criticizes the previous presidents for preventing North Korea to improve their weapons.

His victory was bolstered by strong support from younger people, according to the exit polls. Many of his supporters participated in big, peaceful weekend rallies over the last few months of 2016 and early this year, demanding Park step down. There are only few from the 60s to 70s who voted for Moon. The old ones are not that confident for Moon because of his less argumentative stand on North Korea.
