You don't need to be that "advanced" to cause real trouble to other countries around the world, and strong countries generally have more stake in the international and are less likely to rock the boat, which in turn favors other strong, status quo powers. From the US point of view, Putin isn't a friendly guy, but today's Russia is far better for the US than a weak, divided one full of Russian Orthodox extremist groups bent on exporting the traditionalist revolution across the world. Likewise, it's not like even the strongest possible Syria would pose a "real problem" for the likes of US, Russia, the EU or China.
