Writing at Zuerst, Alexander Dugin connects the destruction of Assad's regime in Syria with the destruction of Europe:
We must bear in mind what the total collapse of Syria would entail. This would automatically trigger the collapse of all other Muslim states in the region; even North Africa would be completely thrown into chaos, as we have already seen in Libya. We can, therefore, speak of a chain reaction or a domino effect in the event of Syria’s collapse. This, in turn, would mean that millions of refugees and migrants would march toward Europe, because there would be no more future for these people in total chaos.
The American-created chaos is thus directed not only against the Middle East and Central Asia, but also against Europe. The more chaos and disorder in the Middle East and North Africa, the more migrants will come to Europe. This, in turn, will lead to the destabilization of social infrastructure and, therefore, to the political paralysis on the European continent. And here we should not forget that thousands of terrorists flow into Europe as part of the migration process. Should this trend continue, and with the future arrival of 10, 20, or even 30 million immigrants coming to Europe, this would actually mean the end of Europe. The European continent would not be "Islamized" per se, nor would a "Caliphate" be built, but instead Europe would sink into total chaos and be wiped out.
Today, Russia is fighting against this development, which is in Europe's interest as well. Russia needs Europe, and Europe needs Russia. Europe's collapse is bad for Russia, and the same notion applies the other way around, even if it is not accepted by many European governments today, which are even working against it. There also is some historic continuity: in the past, Russia saw Europe as a shield against Turkish Ottoman expansionism. Europe sinking into chaos automatically meant Russia being threatened at its western and southern borders. Hence, the protection of Europe is in the interests of the Russian Federation. In order to preserve Europe from falling into chaos, today’s Russia is the shield of the European continent.
Therefore, Russia is fighting in Syria on a number of levels: we are actively taking up the fight against global and hegemonic aspirations of the U.S.; we are protecting our own national and Eurasian security interests by fighting the enemy before it can come to us; we are preserving Europe ahead of its decline because such a development would be harmful to us as well.
