Because the war had begun, the military began to devote itself to the counter offensive, and Chen Xin was busy.

But this time, he doesn't have to go to the front line or take charge of all aspects of work. After all, it's domestic. These things are being done, and the situation in Yanguo is much better than that in Europe, and there are few things to worry about.

Therefore, although a lot of work has been piled on Chen Xin's desk, he can still think about the defense in the Middle East after handling his work.

The so-called Middle East refers to some areas from the eastern and southern Mediterranean to the Persian Gulf Coast, including most of West Asia except afghanistan, Egypt in Africa and the Outer Caucasus on the border with Russia.

This area connects the three continents of Asia, Europe and Africa. Since ancient times, it has been a transportation hub between the East and the West. It is a place of "two oceans, three continents and five seas", and its strategic position is extremely important.

In 1902, the English geographer and Geopolitician Harford mackind put forward the world island theory, which regarded the three continents of Asia, Europe and Africa as a world island, and the Middle East is the center of the world island.

In the world island theory, whoever controls the center of the world island can then control the whole world island and the whole world.

In the age of cold weapons, limited by the problems of transportation, science and technology and productivity, no country can control the center of the world island. However, in history, it is still an important traffic artery connecting the three continents of Asia, Europe and Africa, and this position continues to this day.

However, with the development of history and the continuous improvement of productivity, even without the world island theory proposed by Harford mackind, this land has always been coveted.

From the sun never setting empire of "God, I have the right" to the two superpowers competing for world hegemony after World War II, almost all the wars in this land since World War II are the mess left by the English occupation of this land and the wars provoked by the struggle between the Federation and the Soviet Union for world hegemony.

From this, we can also see how important the strategic significance of this region is.

For the world after the disaster, this region is still an important transportation throat. Even if you can go from Russia to Europe, and Africa has cut off all information exchanges, the Middle East still has very important strategic significance.

After all, alien creatures can invade the Middle East from the Mediterranean. After that, as long as they cross the Arabian Peninsula and the Iranian Plateau, they will have no obstacles, whether they attack the Indian peninsula south or central Asia north.

The only possible obstacle may be the Himalayas, known as the roof of the world, which can rely on the terrain to prevent alien creatures from moving eastward and penetrate the Qinghai Tibet Plateau.

This situation really confirms Harford mackind's World Island theory. Whoever controls this area can control the three continents of Asia, Europe and Africa and the whole world island.

This is the worst case for humans.

At present, human beings have built two important defense lines, one along the North Bank of the Mediterranean and the other across Eastern Europe. Although the southern end of the Eastern European defense line extends towards the Middle East, it only extends near the great Caucasus mountains. With the help of the terrain of the mountains, it can block the advance route of alien organisms.

If we can't block alien creatures on the Mesopotamian plain, once they cross the Iranian Plateau, it means that the whole Asian continent is open to alien creatures.

Therefore, the current plan of Yanguo is to solve the problem of Dongting Lake area as soon as possible, and then use troops and resources for defense in the Middle East.

However, there are disputes about how to build the defense line in the Middle East.

At present, the most effective way is naturally to build a defense line in the Zagros Mountains on the west side of the Iranian plateau with the help of terrain, and then connect it with the greater Caucasus mountains of the Eastern European defense line to form a whole. If alien creatures really attack from here, they can block alien creatures on the Mesopotamian plain.

But some high-level officials in China think it is too far to build the defense line in this way.

They felt that Yanguo should not go so far away from the Middle East to build a defense line, but should build a defense line along the Himalayas and guard the border.

If only in terms of the length and quantities of the defense line, there is not much difference between the Zagros Mountains and the Himalayas.

Both are mountainous terrain, and the length of the defense line is not much different. The terrain of the Himalayas is even steeper, and the construction of the defense line is more conducive to defense.

But if you compare the location on the map, you will understand that if you only build a defense line in the Himalayas, it can really block the route of alien creatures attacking Yanguo eastward and protect Yanguo's own home.

But at the same time, Central Asia and the Indian peninsula are not fortified areas for alien creatures passing through the Middle East.

Even because the ocean surface is frozen, alien creatures can invade Southeast Asia as long as they run a little farther east.

In Chen Xin's view, the location of the defense line is indisputable. Repairing the defense line in the Middle East can effectively connect with the defense line in Eastern Europe, which can not only enhance the defense effect of the defense line, but also unite with allies, and make the defense line guard more regions.

It can be said that repairing the defense line in the Zagros Mountains in the Middle East is a matter of killing many birds with one stone.

But if the defense line is retreated to the Himalayas, the role of this defense line will be greatly reduced.

Not to mention that the two regions of Central Asia and the Indian peninsula will directly lose their barriers. The attack of alien creatures is unimpeded. It is just that the matter of allowing alien creatures to pass through the Middle East itself has a very significant impact on the country.

The most intuitive point is that when central Asia and the Indian peninsula are captured, the inflammatory country will face alien creatures attacking from three directions.

This will undoubtedly greatly increase the consumption of combat for Yanguo.

And have enemies in front and rear of the Central Asian region, and then they can continue to go up to Lucia. Lucia will face the situation of being caught in the back and belly, and it is likely to lose territory of Europe, lose the best land of their own, and even the whole country will fall into this trap.

Chen Xin really doesn't understand why senior management have different opinions on this matter. Is it true that some people are so short-sighted?

Or does someone play an ignominious role and intend to seek benefits from it?

But the problem is that alien creatures are just a group of beasts like insects. Even if human beings want to sell national interests and take refuge in alien creatures for private interests, it is impossible!
