Doomsday Bunker Upgrade Chapter 703: The center of the world island

Because the war has started, the military has begun to fully invest in the counter-offensive, and Chen Xin is also busy.

But this time, I don't need to go to the front line, and I don't need him to be responsible for all aspects of the work. After all, it's a domestic country, and people are doing these things. Moreover, the situation in the Yan Kingdom is much stronger than that in Europe. There are many things to worry about. few.

So although there is a lot of work piled up on Chen Xin's desk, he can still think about the defense of the Middle East after finishing the work.

The so-called Middle East refers to the part of the region from the southern part of the eastern Mediterranean to the coast of the Persian Gulf, including most of West Asia except Afghanistan, Egypt in Africa, and the Transcaucasus region on the border of Russia.

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

In 1902, the English geographer and geopolitical scientist Halford Mackinder proposed the world island theory, which regarded the three continents of Asia, Europe and Africa as a world island, and the Middle East was the world center of the island.

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

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

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

From the "God has God, I have the right" empire where the sun never sets, to the two superpowers competing for world hegemony after World War II, since World War II, almost all the wars that have occurred in this land have been when England occupied this land The mess left behind, as well as the wars provoked by the Federation and Suvia's struggle for world hegemony.

This also shows how strategically important this area is.

For the world after the disaster, this area is still an important traffic choke point. Even if you travel from Yan Kingdom to Europe, you can go through Lucia. Africa has cut off all information exchanges, but the Middle East still has a very important strategic significance.

After all, alien creatures can completely invade the Middle East from the Mediterranean Sea. After that, as long as they pass through the Arabian Peninsula and cross the Iranian plateau, whether they are attacking the Indian Peninsula in the south or attacking Central Asia in the north, there is no obstacle.

The only possible obstacle may be the Himalayas, known as the roof of the world, which can block the eastward advance of alien creatures and penetrate the Qinghai-Tibet Plateau by virtue of the terrain.

This situation really confirms Halford Mackinder's world island theory, whoever controls this area can control the three continents of Asia, Europe and Africa, and control the entire world island.

And that's the worst-case scenario for humans.

At present, there are two important defense lines built by human beings, one is built along the northern coast of the Mediterranean Sea, and the other is across Eastern Europe. Although the southern end of the Eastern European defense line is extending towards the Middle East, it currently only extends to the vicinity of the Greater Caucasus Mountains. The terrain can block the path of alien creatures.

If aliens cannot be kept out of the Mesopotamian plains, once they are allowed to cross the Iranian plateau, it means that the entire Asian continent is open to aliens.

So the current plan of the Yan Kingdom is to solve the problem in the Dongting Lake area as soon as possible, and then use the army and resources for the defense of the Middle East.

It's just that there is a debate about how to build defenses in the Middle East.

At present, the most effective method is naturally to build a defense line in the Zagros Mountains on the west side of the Iranian Plateau with the help of the terrain, and then connect it with the Greater Caucasus Mountains of the Eastern European Defense Line to form a whole. If alien creatures really Attacking from here, aliens can be kept off the Mesopotamian plains.

However, some high-level officials in China think that the defense line is too far.

They felt that the Yan Kingdom should not go as far as the Middle East to build a defense line, but should build a defense line along the Himalayas and guard the border.

The Zagros Mountains and the Himalayas are not much different in terms of the length and engineering of the line of defense.

Both are mountainous terrain, and the length of the defense line is not much the same. 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 positions on the map, you will understand that if you only build a defense line in the Himalayas, it can indeed block the route of alien creatures from eastward to attack the Yan Kingdom, and protect the Yan Kingdom's own homeland.

But at the same time, Central Asia and the Indian peninsula are undefended areas for aliens that pass through the Middle East.

Even because the oceans are frozen, alien creatures can invade Southeast Asia just a little further east.

In Chen Xin's opinion, the location of the defense line is undisputed. Building the defense line in the Middle East can effectively connect it with the Eastern European defense line. It can not only enhance the defense effect of the defense line, but also unite with allies. It can make the defense line protect more areas.

It can be said that building a defense line in the Zagros Mountains in the Middle East is a multi-pronged thing.

But if the defense line is retreated to the Himalayas, then the role of this line of defense will be greatly reduced~IndoMTL.com~ Not to mention that the two regions of Central Asia and the Indian Peninsula will directly lose their barriers, and the alien creatures' The attack is unobstructed, and the fact that alien creatures pass through the Middle East has a very significant impact on the Yan Kingdom.

The most intuitive point is that after Central Asia and the Indian Peninsula are captured, the Yan Kingdom will face alien creatures attacking from three directions.

For Yan Kingdom, this will undoubtedly greatly increase the cost of combat.

And after the alien creatures have captured Central Asia, they can continue to go north to Lucia. At that time, Lucia will face the situation of being attacked by the enemy, and it is very likely that they will lose the territory of the European region, lose their most elite country, and even lose their most important country. It's the whole country that has fallen.

Chen Xin really hates to understand why the high-level people have different opinions on this matter. Is it true that some people are short-sighted to this extent?

Or, is someone playing some disgraceful role in this, intending to benefit from it?

The problem is that alien creatures are just a group of beasts like bugs. Even if human beings want to sell their national interests and rely on alien creatures for personal gain, it is impossible!
