It seems the general idea in this thread is that this issue is guided by more factors than brute military force, which I am glad to see. Maybe because of the internet, the public seems to have much more information about the intricate details of the situations than earlier generations would have on earlier issues.
My view on this is that a proxy war will/would be the height of military escalation here, largely due to current generation military tech. One embarrassment of the cold war era is the time Russia confused a US military drill for a nuclear attack. Current sensory equipment is immensely more sophisticated, especially the tracking of small things in orbit.
Much modern military tech focuses on shielding an area from attack. The advancements in offensive technology have created extremely powerful and stealthy weapons (like the modern submarines, hypersonic missiles, cybernetic attacks (Stuxnet), EMP weapons, telecommunications jamming). The bonds of the global economy also work to keep large scale wars in check, though this has more grey areas.
I see the public awareness of the issue as a large positive force here, as an ignorant public may not oppose its government going war. Again though, the grey areas. International conflicts are never as simple as an easy summary given in a news report. I am hopeful about it though, since so many minds are working on this. That said, the degrading relations between the Russian and American space agencies saddens me.
