Agreed that he's far less terrible than Obama kamikaze but still not what we all hope for.
Yeah, he's still very pro-war, but better than average, and better than all but a small handful of the Dem candidates.
I think that Sanders is intuitively much more anti-war than Trump, but he'd also be more willing to be a mere cog in the machine, which might give results similar to Obama. Not sure.
Anyway USA turning socialist might create the best possible country in the world. Only troubles of USA are the undless wars, the lack of welfare and the complete inhuman way of treating citizens. Without that it might become a super country 
Even if Sanders wins, the US is not going to become socialist overnight (thank goodness...). The Senate, Supreme Court, and (periodically) the House will block basically every little thing he does. If he plays his cards right, he might be able to push through one or two major things, but it won't be exactly what he wants, and it's not going to completely reshape US politics.
