At the same time that the three major powers of Tang, the United States, and the Soviet Union were engaged in space hegemony, the earth was still full of wars, and wars between countries of various sizes were continuous.

Since the end of the Korean War and the Mongolian War, the Soviet Union's military operations on the ground have been somewhat restrained, and it has no longer advanced in the direction of Asia, avoiding confrontation with the Tang Empire, but turning to Europe and Africa, continuing to promote Soviet hegemony and confronting the United States and NATO.

After the establishment of NATO by the United States and European countries, their military strength increased dramatically, and Britain and France gradually recovered with the assistance of the United States.

However, with the end of World War II, the power of traditional powers such as Britain, France, Germany, and Italy was seriously weakened, and large-scale wars of liberation were launched in their colonies, and countries such as India and South Africa gained independence one after another.

In Southeast Asia, Singapore, Malaya and other countries gained independence with the support of the Tang Empire, which made Britain very annoyed, because Britain's only naval military base in Asia, Singapore, which guarded the Malacca waterway, fell to the Tang Dynasty, so that the Tang Empire Navy was stationed in Singapore and seized the naval and air bases built by the British at great expense.

It was a huge fortress that guarded the Malacca waterway, and its strategic location was extremely important, and with the Tang army stationed there, it marked the Tang Empire's complete control of the main energy communication routes from the Asia-Pacific region to the world.

The British were not willing to withdraw from Asia like this, but the United States did not want to confront the Tang Empire over Singapore. But soon one thing changed the position of the United States, the revolution broke out in Vietnam, affecting the American Philippines, France sent troops to suppress it, and Vietnam and China are separated by mountains and rivers, and the federal China relied on the support of the Tang Empire to achieve great military success in the two wars of Korea and Mongolia, and the military strength increased dramatically, coupled with the economic assistance of the Tang Empire to China, which made the federal economy China's economic strength increase, and the mind of the great power of the Celestial Empire began to make trouble, and he simply looked down on the strength of the French army, at the request of the Vietnamese Revolutionary Army. ** Sent troops to Vietnam to fight the French army.

** All Tang advanced weapons and equipment, much ahead of the French army, plus occupy a geographical advantage, seven battles and seven victories in three months, in one fell swoop, the French ** team was driven to a small place in the south, and it was about to be wiped out.

At this time, the United States couldn't help it, after all, the United States is the boss of NATO, and the Tang Empire directly supported Singapore's independence. Drove out the British. This has already slapped the Americans in the mouth. Losing face to the Eisenhower administration. Now that China has sent troops to resist France and aid Vietnam, if the United States does not care about it, then NATO will fall apart, especially since the Soviet Union established the Warsaw Pact. At this time, the United States cannot be softer.

At the critical moment, the US military was dispatched.

The U.S. Navy's Third Fleet in Subic Bay quickly rushed to southern Vietnam, and when the French army was about to be completely annihilated, it suddenly intervened by force, taking the squadron by surprise and causing heavy losses.

This incident shocked the world, and the media around the world speculated whether a war would break out between the Tang Empire and the United States.

Zhang Meng immediately had a telephone conversation with Eisenhower, making clear the position of the Tang Empire and demanding that the US military stop intervening in the Vietnam War.

Eisenhower wanted to be re-elected as the next president. So he was resolute, and even did not hesitate to fight with the Tang Empire, but he didn't say it too much, but tactfully pointed out that the Tang Army had intervened in the Singapore and Malayan revolutions before. led to the withdrawal of British troops, and the United States did not say anything at that time. Therefore, on the issue of the Vietnam War, this time it was the turn of the United States to send troops, hoping that the Tang Empire would not interfere.

Zhang Meng was focused on outer space at this time, and the unknown things on the moon made him nervous, so he saw Eisenhower's euphemistic attitude, and Vietnam was not the core interest of the Tang Empire, Zhang Meng was also curious about whether he could defeat the US army, and he also wanted to see the combat effectiveness of the US army, so he was not too tough.

However, Zhang Meng said that the US military must not expand the war and spread it to China, otherwise the Tang army will have to intervene.

Eisenhower was also in a cold sweat, for fear that Zhang Meng would be unhappy and would PK with the United States, but fortunately, Zhang Meng's attention was all focused on outer space, so as to avoid a direct military conflict between Tang and the United States.

Of course, Eisenhower knew very well in his heart that even if the Tang Empire did not send troops to intervene, it would also assist China and Vietnam in terms of economy and weaponry, and this Vietnam War was an uncertain factor, once it was won, it would be extremely beneficial to the hegemony of the United States, but once it lost, the consequences would be very serious.

But Eisenhower doesn't care about that, as long as he is tough, it will be of great help to his re-election, as for whether he can win or not, it doesn't matter, anyway, he can't be re-elected three times, if he wins, he earns, and if he loses, let his successor have a headache.

The United States, which has a powerful navy and air force, soon sent 5 aircraft carriers, 10 battleships, and more than 100 other auxiliary ships to Cam Ranh Bay to seize sea supremacy. The Federal Chinese Navy was still very weak, and only some of the warships eliminated by the Tang Army were in service and did not participate in the war.

In the air, the US military sent more than 850 planes from the Philippine mainland, plus the aircraft carrier force, for a total of more than 1,000 aircraft. Vietnam had no air force at all, and China sent more than 1,000 planes to participate in the war, and the air power of the two sides was roughly balanced.

The ground troops have become the main battlefield of the fighting, and the 3 million Chinese and Vietnamese troops are fighting in the jungle with the 900,000 troops of the United States and France.

Some planes, tanks, missiles, and helicopters of the US military appeared one after another, and the Tang Army soon had a general understanding and assessment of the actual combat effectiveness and scientific and technological level of the US military.

Due to the economic and military support of the Tang Empire, the Chinese and Vietnamese armies were able to continue to compete with the American and French armies, which plunged the Vietnam War into a protracted war, and it did not distinguish the winner after five years.

The Tang Empire has never been directly involved, and five years later, it was attracted all the attention of the moon in outer space, and all military operations on the earth were stopped, and the Tang Army's various weapons and equipment began a new round of upgrading, and the target was more unconventional weapons, aiming at space.

This is because the Datang Empire launched the first lunar exploration reconnaissance satellite in human history, and found an unidentified object impact site on the far side of the moon.

Due to the strict secrecy of the Tang Empire, Zhang Meng ordered the Tang Army to be prepared for battle in case of war with extraterrestrial life, so the Tang Army made every effort to develop unconventional weapons, such as nuclear missiles, death light, laser cannons, electromagnetic railguns, space vehicles, etc., which was considered a new round of arms race by the United States and the Soviet Union, although they did not understand what was behind the moon, but had to compete with the Tang Empire.

As a result, the United States and the Soviet Union frantically developed nuclear weapons, stockpiled tens of thousands of nuclear warheads, and at the same time did not hesitate to spend huge sums of money in the research of cutting-edge science and technology such as death light, laser cannons, railguns, and space vehicles.
