The latest information about whether North Korea and South Korea can fight.

I can't fight. Because militarily, North Korea has always been a closed country, and the military facilities and bunkers on its territory have always been kept secret. The United States and North Korea have been using satellites and planes to detect North Korea, which is very different. If we invade Korea rashly, the attack of the US and South Korean troops will be seriously frustrated and fall into the quagmire of guerrilla warfare. Obama hasn't climbed out of the tomb of Afghanistan (Afghanistan is known as the "imperial tomb"), just like jumping into the mire? Unless Obama is crazy. Politically speaking, the United States has kept the appreciation of RMB very tight, pushing up prices in China with 300 billion dollars. China's goal of controlling inflation and austerity has become a joke. It is bound to encourage North Korea to shell South Korea, take the opportunity to warn the United States, pull Russia into the water, and divert pressure. Russia and Japan have territorial disputes in the north. Behind Japan is the United States. It is hard to say that Japan's sudden toughness has no "will" from the United States. The United States has always hoped that Japan would recover the northern territory to contain the Russian Sea of Okhotsk and monitor kamchatka peninsula. Did Russia warn the United States not to encourage Japan to make a fuss about the northern territory in this shelling incident? After all, in the US-Japan military exercise, Russian planes flew by, and the exercise was also called "seizing the island". Whose island has been occupied? Japan and the United States tacitly, but Russia and China can't sleep well! Historically, the United States has been deeply involved under the pretext of crisis. This shelling incident on Yeonpyeong Island is a rare opportunity. However, if South Korea's military provocation is ignored, it will inevitably lead to military out of control. The only way to bring the situation back under control is to negotiate with China, let China suppress North Korea, or take direct dialogue with North Korea to solve it. So the U.S. Secretary of Defense 2011came, and the U.S. governor also came to North Korea. South Korea's military exercise became a one-man show, and Lee Myung-bak's plan to drag the United States into the water and let the world see the true face of North Korea also fell through. On the contrary, North Korea eased up, while the United States said it did not believe that North Korea would abandon its nuclear program. Japan has also lost its place. How to fight this battle? What's the name of South Korea sending troops to North Korea? Punish North Korea? Or liberate the Korean people? Will America agree?
