Doomsday Bunker Upgrade

Because the war had already started, the military began to devote all their efforts to the counterattack, and Chen Xin also got busy.

But this time, he doesn't need to go to the front line, and he doesn't need to be responsible for all aspects of work. After all, it's in China, and there are people doing these things, and the situation in Yan Kingdom is much stronger than that in Europe, so there are very few things to worry about.

So although there was a lot of work on Chen Xin's desk, he was still able to think about defense in 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 Russian border.

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 land of "two oceans, three continents and five seas", and its strategic position is extremely important.

In 1902, 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 center of the world island .

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

The era of cold weapons is limited by the problems of transportation, technology and productivity. No country can control the center of the world island. However, it is still an important traffic route connecting the three continents of Asia, Europe and Africa in history. It continues to this day.

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

From the empire on which the sun never sets that says "God is in the sky, I have rights" to the two superpowers competing for world hegemony after World War II, almost all the wars that have occurred in this land since World War II are left over from the British occupation of this land The mess, and the chaos caused by the Federation and Suvia's struggle for world hegemony.

From this, it can also be seen how important the strategic significance of this area is.

For the post-disaster world, this area is still an important transportation throat. Even if you can go to Europe from Yan Country through Lucia, and Africa has cut off all information exchanges, the Middle East region still has very important strategic significance.

After all, alien creatures can completely invade the Middle East from the Mediterranean Sea, and then as long as they pass through the Arabian Peninsula and the Iranian Plateau, whether they attack the Indian Peninsula southward or attack Central Asia northward, there will be no hindrance.

The only thing that may be an obstacle is the Himalayas, known as the roof of the world, which can block alien creatures from advancing eastward and penetrate the Qinghai-Tibet Plateau.

Such a situation really confirmed Halford Mackinder's theory of the world island. Whoever controls this area can control the three continents of Asia, Europe and Africa, and control the entire world island.

And this is the worst case scenario for humans.

At present, there are two important defense lines built by humans, one is built along the northern shore 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 only extends to the vicinity of the Greater Caucasus Mountains. Alien creatures are out of the way.

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

Therefore, Yan Kingdom's current plan is to solve the problems 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 currently controversy about how to build a defense line in the Middle East.

At present, the most effective method is naturally to build a defense line on the Zagros Mountains on the west side of the Iranian Plateau, and then connect it with the Greater Caucasus Mountains part of the Eastern European defense line to form a whole. If alien creatures really attack from here , the alien creatures can be blocked on the plains of Mesopotamia.

However, some high-level officials in the country think that this line of defense is too far away.

They felt that 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 to protect the border.

In terms of the length and engineering volume of the defense line alone, 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 too different. The terrain of the Himalayas is even steeper, and it is more conducive to defense if the defense line is built.

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 indeed block the route of alien creatures from eastward to attack Yan Kingdom, and protect Yan Kingdom's own homeland.

But at the same time, Central Asia and the Indian Peninsula are undefended areas for alien creatures passing through the Middle East.

Even because the ocean surface is frozen, alien creatures can get their hands on Southeast Asia as long as they run a little further east.

In Chen Xin's view, the location of the defense line is undisputed. Building the defense line in the Middle East can effectively connect with the Eastern European defense line. Lines of defense guard more areas.

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

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

Not to mention that Central Asia and the Indian peninsula will lose their barriers directly, and the aliens' attack will be unimpeded, but the matter of allowing aliens to pass through the Middle East is of great significance to the Yan Kingdom. very significant impact.

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

For Yan Country, this will undoubtedly greatly increase the consumption of combat.

Moreover, after the alien creatures capture Central Asia, they can continue to go northward to Lucia. At that time, Lucia will face the situation of being attacked from both sides. It is very likely that they will lose the territory of Europe, lose their most essential land, or even the entire country. All fell down.

Chen Xin really couldn't understand why the top management had different opinions on this matter. Could it be that some people were so short-sighted?

Or is there someone playing a disgraceful role in this, intending to gain any benefit from it?

But the problem is that aliens are just a group of beasts like bugs. Even if human beings want to sell their national interests and seek personal gain from aliens, it is impossible!
