According to former US commander, American could lose a war against North Korea. according to retired Lt Gen Jan-Marc Jouas, US military outnumbered and out-supplied if attack North Korea. His letter to newsweek also said Donald Trumph should believe that US better build peace than war to North Korea.
If Donald Trumph want to win against North Korea, he needs Indonesia I think. Why? First, Indonesia has many islands can supplied US army to attack North Korea. 28,500 Personel in South Korea is not enough against North Korea. Second, Indonesia has many forests and its same like North Korea. It is useful for US army to know how to handle North Korea army.
I believe that without Indonesia support, US would lose war against North Korea. I think, Donald Trumph should make deal with Joko Widodo to win against North Korea. Indonesia has Islands can using as military base. So, Donald Trumph needs Indonesia to win against North Korea.
