Two things are contended: one is hegemony, the other is a strategic space.
First, hegemony.
After the Second World War, the earth has sprung up two superpowers, the United States and the Soviet Union. The two old rogue in order to seize the right of absolute control of the earth, have been established in NATO and the Warsaw Pact of the two military organization, each led a group of younger brother, infighting, dog bukekaijiao, the whole world is living behind the iron curtain under complete darkness.
After the collapse of the Soviet Union, Russia became the successor of the Soviet Union. It not only inherited most of the Soviet Union's vast territory, assets and nuclear weapons, but also inherited the Soviet ambitions for hegemony. Therefore, although Russia's strength has been shrinking, Russia will not give up its ambition of controlling the earth, and has been fighting against the US in all directions. The United States also regards Russia as the biggest challenger of its hegemony, and the most dangerous enemy of the US and the European Union.
While the United States and Russia in the Syria battle, Francis, is the extension of the two hooligan competing for hegemony.
Then we talk about the strategic space.
What is the most important thing for a big country? A lot of people will say, it's the strength! The answer is right, but it's not right. For example, in the field of Syria, Russia dispatched a large number of regular army and armed mercenaries to Syria, and the United States, Israel, Saudi Arabia, Qatar, United Arab Emirates, the European Union and Turkey to support all kinds of terrorist organization, the opposition, on the battlefield to fight alone in the fight at outrance, military power, the Russian side is occupied the advantage of playing for more than two years, the result? A few days ago, Putin visited Syria and announced that the Russian army would withdraw from Syria by the end of the year and return to his country. And occupied half the Syria territory of the east side of the Euphrates River, where dozens of military bases were established, and the elder and Defense Secretary James Mathis responded openly to Russia's withdrawal request: resolutely no withdrawal. It is clear that we should occupy the half of the Syria openly, and try our best to drive the Russian troops stationed in Syria's military bases out of Syria to eliminate the influence and strategic space of Russia in the Middle East. The military strength of the dominant Russians after more than two years, a lot of people died, including a will, all in vain, so, regret past doings?
Why did Russia fall like this? The answer is - strength, dare not, no determination to use strength, everything is a swollen face to be fat, not to be killed by the enemy. In the 50s war, a great leader of the east country, in the face of great danger and pressure, courage, firmly power, firmly send troops into enemies, and fight to the end, all over the world to see. This is the real power of a big country!
In September 2015, why did Russia send troops to fight in Syria? It is the strategic space for the protection of Russia. Because of NATO's eastward expansion, the strategic space of western Russia (Eastern Europe and the Baltic Sea) is basically eaten up by NATO led by the United States. Almost all the enemy have reached home, and national security is threatened greatly.
Under such unfavorable situation, the strategic space of the southern part of Russia (Caucasus and Syria / Middle East) is crucial for Russia's national security. Russia has a military base in Syria, which is also the only fulcrum for Russia to play a big power in the Middle East and the Mediterranean, and to defend the strategic space of the south. If Russia is out of Syria, no military presence, not only the world's superpower completely finished, and the national security also was a big hole, Russia is likely to be the United States, the European Union dismembered into several semi colonial countries, at least, Chechnya and Ingushetia Republic in the US and Europe under the support of independence from Russia go out.
Therefore, the Russians should exert their efforts to maintain their military presence in Syria. Assad, President of Syria, is to protect their strategic space for big powers.
In order to pursue hegemony, in order to defend the strategic space of the south, the Russians even hungry, had to bite the bullet, in Syria and the United States fight to the end!
