Surprise Attack
› Chinese Intervention
First Phase Offensive, Battle of Unsan (China
attacked the Republic of Korea 1st Infantry
Division at Unsan on October 25. This resulted in
surprising the United Nations forces and surprising
the US 8th Cavalry Regiment. As a result, this
became one of the most desolating US loss in the
war.)
Chinese New Year's Offensive
PVA(People’s Volunteer Army—China) and the
KPA(Korean’s People’s Army—North Korea) attacked UN
command
North Korea strategically asked Soviet
Union to join them in invading North
Korea. North Korea saw an opportunity
and saw that the best time to attack
would be sooner than later.
– Aggressor nation (North Korea)/nation A
(that wants to change the status quo)
believes that
– status quo nation D (South Korea) is weak
in military capability
The payoff would have an advantage if
one side swerves
Black-North
Korea
Green-South
Korea
Nash Equilibrium (No advancing)
No player wanted to change their
strategy. Little territory was exchanged
Both countries wanted to “beef up” their
military. However, three things took
place.
› an indirect arms race between North
Korea and South Korea
› rising tensions between North Korea and
South Korea (increased violence in each
country..especially around the 38th
parallel
› A war taking place
US President Harry Truman commented
on using the atomic bomb against the
PVA after an attack on the UN
Command by North Korea in hopes to
end the war.
Was this brinkmanship?
The threat to use atomic welfare is a
dominant strategy and is very credible due the
fact President Truman had already used an atomic
bomb before
The battle of the Kumsong ended the war
and started talks in exchanging POW’s
(Hostage-Holding Game—releasing
hostages gives leverage, also gives
bargaining power). Syngman Rhee
agreed to let 27,000 Korean internees
escape. The United States disagreed, but in
the interest of peace, compromised and
signed the agreement. Peng Dehuai for the
China and Kim Il-sung for the North Korea
later signed the agreement.
