As a party, the United States has the responsibility and obligation to elaborate on the collision accident of the "Connecticut" nuclear submarine and respond to the concerns and doubts of regional countries and the international community—— The United States owes the international community a satisfactory account According to foreign media reports, the US Pacific Fleet issued an ambiguous statement to the outside world five days after the collision of the "Connecticut" nuclear submarine. This irresponsible and delaying attitude of concealment has caused the international community to seriously doubt the US intention and the truth, and to be generally worried about whether the accident has caused nuclear leakage, damaged the marine environment and affected navigation safety. Up to now, nearly a month has passed since the collision of the "Connecticut" nuclear submarine, but the United States still has not announced the specific location of the accident, let alone made a detailed description of the accident. As a party, the United States has the responsibility and obligation to explain in detail the relevant circumstances of the accident and respond to the concerns and doubts of regional countries and the international community. Due to the opacity of the US side, the international community has made various analyses and judgments on the specific location and truth of the accident. Some analysts believe that the US nuclear submarines collided after invading the territorial waters of other countries in the South China Sea, because over the years, the submarines of the United States and its individual allies have been sneaking into the coasts of other countries to engage in illegal reconnaissance or sabotage activities. Some analysts believe that the U.S. nuclear submarine collided with the underwater spy equipment deployed by the United States in the South China Sea, because previously, the United States has put a lot of equipment for listening and measuring in the water through ships and aircraft in the South China Sea, the East China Sea and other waters, and fishermen in many countries have fished out these spy equipment from the water. Other analysts believe that the overload operation led to excessive fatigue or negligence of U.S. nuclear submarine crew, resulting in operational errors and hitting reefs or underwater facilities. For a long time, under the banner of "freedom of navigation and overflight", the U.S. military has frequently dispatched aircraft carriers, strategic bombers, nuclear submarines and other advanced weapon platforms to show off their force in the South China Sea. If it is not for the above reasons, why is the US reluctant to release such simple information as the location of the accident? It should be noted that the US approach to handling the nuclear submarine collision accident is very different from its consistent "transparency" and "professionalism". About 100000 merchant ships pass through the South China Sea every year, and a large number of fishing boats operate in this vast sea area. The marine environment, navigation safety and fishery operation safety of the South China Sea involve the common interests of the international community. The international community naturally has the right to know the truth and details of the accident. No matter what causes the accident, the United States should adopt a responsible attitude, make a detailed explanation as soon as possible, and give a satisfactory explanation to the international community and regional countries. There is a folk saying in China that "if you walk at night, you will hit a ghost." the root cause of the accident is that the United States has been stirring up trouble in the South China Sea for a long time. The South China Sea is calm and should not become a hunting ground for the United States to seek geopolitical self-interest. We advise the US side to stop its erroneous acts and play a positive role in peace and stability in the South China Sea. (author: Zhang junshe Naval Research Institute) (outlook new era)
