Syria is Russia's regional ally. They're the only place outside the former USSR housing a military installation - a naval base which gives Russia a port with Med access that's not reliant on Turkish permission. They've been quite friendly with Russia historically, even to the point of refusing to allow gulf oil to pipe through their country because it would hurt the Russian economy. Russia likewise has written off billions of debt from them. With Russia's other major port in the Crimean peninsula they were willing to absolutely tank long-term relations with Ukraine and short-term relations with the west, zero fucks given, when Ukraine started bailing on their sphere and wanted to renegotiate terms regarding Sevastopol. At this point, we KNOW they will not back down over Tartus either.
The situation for Russia is the Baltic states joining NATO, Turkey becoming more hostile and threatening, China increasing power in the pacific, and now Syria has the potential to collapse into either a Saudi puppet, anarchy, or a jihadist mix of the two. This is unacceptable to them. We can bitch and moan about how they're bullies and it's their fault - it's still unacceptable to them. They cannot back down. If they allow the USA, Turkey, and Saudi Arabia to destroy their literal best friend they are done as a force of influence and lucky to only go back to 1991 levels of being pushed around again. They have to AT LEAST put up enough of a fight that it is clear they only lost because America won - no other loss can be stomached.
I know I can sound like a crackpot at times but this much at least isn't speculative or tin foil. Russia literally can and will not allow itself to lose to nobodies - if Syria goes down, it must be to an opponent of the caliber of the USA (maybe a coordinated EU could suffice). If we want to actually win in Syria - which for Obama is Assad out and someone who will play economic ball with Turkey and SA in - we have to use enough force for Russia to be able to publicly state that the USA went in there in force. How do you do that when Russia's right there without sparking war? I don't fucking know.
This part I don't believe, I just kind of wonder: The first world war was sparked by Germany taking actions that they knew would cause Russia to flinch. The Tsar was in a very weak position and everyone knew it. He could not suffer a humiliation. When Austria stumbled into a chance to push, Germany knew with certainty that Russia HAD to stand up for Serbia, because they'd run out of leeway to let these things slide. If the precursor events to WWI had taken place before the Balkan wars, Russia MIGHT have backed down, and if before 1905 they WOULD have backed down. Not in 1914. They had to at least make a show of defending Serbia. Germany knew this, and pushed the Austrians in, and Russia responded with their full mobilization which Germany promptly responded to it... with invading France and Belgium.
So anyway, my worry is, here we are: the US dollar appears to be only potentially getting weaker. Our debt is so bad we've shit on interest rates so that our debt interest payments can stay low. Our economy is being passed by China and is looking to be outpaced by others in our lifetime. Throw in the cold war's end and now we're both economically and militarily seen as obsolete by most of the world. Nobody else really feels like they need to prop up the dollar. Few feel like our unmatched military is a necessary or good thing anymore. Our time is passing. What if (and again I don't REALLY think this, just kinda worry) we are taking similar steps to Germany in trying to provoke a conflict while we're still relevant and superior? What if the goal of western elite IS for conflict, they're just trying to provoke it because they don't want to be the instigators?
