It's not clear to me what this means.
If it means that Obama would like to steer the ideology of the US military leftward, I can certainly believe that.
If it means he wants to strengthen the US military, that idea does not seem to fit, since he wants to cut weapons research.
If it means that he will lead the USA into a military defeat, as Trotsky did in World War I, well, I don't know. The US military, for now, can certainly hold its own when it is allowed to pick its battleground. It depends on what kind of scenario Obama would put them into.
Also, Trotsky and Stalin eventually were political and ideological opponents. Would the "Stalin" side of Obama's brain order the assassination of the "Trotsky" side?
trotsky was killed by an axe in mexico.

I believe the Stalin-Trotsky analogy is apt also. Not because there is likely to be physical violence or attempted coups at the top but there certainly will be ideological struggles because he who wins those battles captures the apparatus of the United States government and has a real chance at world suzerainty. I have predicted since before the election that we're likely to see these struggles as soon as the left feels that it has extinguished any reactionary threat from the right. We might expect to see that to occur between Hillary and Obama.
