What is the attraction of Afghanistan, the "imperial cemetery" of the three countries?

The three great powers before and after Afghanistan are all due to the high strategic value of Afghanistan's status.

From the beginning of 1839 to the end of 19 19, Britain invaded Afghanistan three times, all of which ended in failure.

From 65438 to 0979, the Soviet Union sent troops to Afghanistan, which aroused the fierce resistance of the Afghan people and ended in failure.

After the 9 1 1 incident, the United States began to carry out military strikes against Afghanistan. After nearly 20 years of fighting, it can only sign an armistice agreement.

Afghanistan is located in the hinterland of Central Asia, and its domestic resources are not rich. It can attract several big countries to take turns. It wants to control Afghanistan because its strategic position is very important.

Afghanistan is a landlocked country with no direct borders with neighboring powers. In this way, no big country can directly control Afghanistan. Moreover, Afghanistan is just at the junction of East Asia, Central Asia, West Asia and South Asia, and it is a veritable strategic location. No matter which side holds Afghanistan, it can expand its strength to the surrounding forces, and it can attack and retreat and defend.

Secondly, Afghanistan's national strength has been relatively weak. This gives the countries that want to occupy Afghanistan the illusion that they can easily annex Afghanistan. So once we get the chance, we will send troops to Afghanistan. However, no big country will tolerate Afghanistan being completely occupied by another big country, which has caused many countries to send troops to Afghanistan, but no country can successfully occupy it.

Third, although Afghanistan is not a Middle East country, it has a great influence on the Middle East. Once Afghanistan is occupied, those small countries in the Middle East will be easily conquered. Historically, Afghanistan is of great military significance to the South Asian subcontinent. It is easier to March from Afghanistan to the South Asian subcontinent than to attack Afghanistan from India.

To sum up, Afghanistan is of great strategic significance to the neighboring South Asian subcontinent and the Middle East, and its comprehensive national strength is relatively weak, attracting many big countries and trying to control Afghanistan.
