1, Vietnam invaded Thailand and was bound to be defeated.
Judging from the current paper military strength, Vietnam seems to be stronger than Thailand. But Vietnam's advantages will be offset by many objective factors. There is no territorial border between Vietnam and Thailand, and the only way for Vietnam to invade Thailand is a bigger sea and sky. In other words, Vietnam must transport a large number of army troops through the navy and air force to complete its aggression against Thailand. With all this, the advantage of the Vietnamese army is gone. Vietnam may not even be able to provide logistics support for its own army. In this way, the result of Vietnam's invasion of Thailand doomed Vietnam's inevitable failure.
Vietnam's aggression against Thailand will inevitably be sanctioned.
In today's international society, although there are wars in some places, the mainstream is definitely peaceful development. If Vietnam openly invades Thailand now, this inhuman war behavior of Vietnam will certainly not be accepted by the international community. The international community must impose comprehensive sanctions on Vietnam within the framework of the United Nations. According to Vietnam's current national strength, it has no strength to bear the comprehensive sanctions of the international community. Under the joint attack of the international community, Vietnam's economy will inevitably collapse.
Vietnam's invasion of Thailand is bound to be opposed by domestic anti-war forces.
At present, peace-loving people are definitely in the majority in a country, and Vietnam is the same. If Vietnam invades Thailand flagrantly, the peace-loving people of Vietnam will certainly hold high the anti-war banner and oppose the invasion by the Vietnamese government. This is a huge force, and the Vietnamese government cannot ignore it. If the Vietnamese government really ignores public opinion, then the Vietnamese government may subvert it.
