It's basically inevitable, the choice is in how we go about it. Hillary Clinton is an opportunistic snake of the highest order, perhaps the very human avatar of the enduring security state establishment.
As you well know, she will make all sorts of idealistic liberal speeches across her campaign, ride the Woman President train to victory, and then promptly turn around wearing her I Heart Drone Strikes shirt like Bush and Obama before her. Now, will Donald do the same? Yeah, pretty much, except he'll wear a tiny predictor drone pin during the campaign instead of waiting for the results.
The key difference is that Hillary is a veteran of politics and Donald is a ham-fisted idiot. He will almost undoubtedly mishandle the power he is granted so horribly that the security state will be left torn open and bleeding out by his unsubtle and prideful actions. This can be weighed against Hillary, who might throw the dogs a bone on something social, I don't know, let's say transgender rights, and by the time her term ends police cruisers will be replaced with DoD surplus and the right to trial will resemble swiss cheese. Unlike Donald, these changes will stay because she won't be dumb about implementing them.
We need that dumb. We need this nascent tyranny to get at the helm someone who will both be willing to use it and is also a total fuckup so that it will at least stop being entrenched.
And I see no man better positioned to fill that role than Donald John Trump.
