What makes this issue of false flag events and ?international incidents? relevant is the fact that the imperialist ruling class will manufacture as many of these sorts of episodes as is necessary for their war. Because of this, it is incumbent on the forces standing in opposition to such aggression to uphold the principles of international law and justice. Syria was well within their rights to shoot down a foreign jet operating within their airspace, just as the US military would be within its rights to shoot down a Mexican warplane within US airspace.
However, this episode is far larger than simply international law. Indeed, it strikes at the heart of the concept of the nation-state. It demonstrates first, the power of the nation, with its leaders, citizens, and institutions to resist the forces of imperialism. Conversely, it shows the existential need of the imperialist ruling class to destroy strong, independent nations that refuse to be enslaved by the forces of finance capital and imperial economic domination. Syria is the frontline of the struggle against these forces, and those who believe themselves to be anti-imperialists must unite to denounce provocations, pretexts, and legitimizations manufactured by the imperialist ruling class and preempt all their attempts to drive the world ever closer to total war.
