In 2008 I was a Clinton supporter throughout most of the primary season

62. If you're going to put these forward as bad decisions on his part

(which they may or may not be, that's open to debate)

then I think the question is, was Hillary against any of these things? Or would she have made what you consider to be the same "bad" decisions?

I'll save you the effort:
...she also voted for AUMF
...she also supported the Kosovo bombing (see http://www.ontheissues.org/Senate/Hillary_Clinton_Kosovo.htm )

I don't know that she's ever spoken out specifically about the Iraq Liberation Act, but since it was Bill's policy AND it was used largely as the basis for the IWR that she did vote for, I think it's pretty safe to assume that she supported it.

I'm not sure what you mean about "expansion" into Afghanistan. The initial action was done via the aforementioned AUMF, which I assume you're not counting twice. Further expansion beyond that was opposed by Sanders, i.e. he opposed the 2009 surge (see http://feelthebern.org/bernie-sanders-on-afghanistan/ ). Hillary, of course, strongly supported the surge.

There are other times that Hillary has supported military positions that Bernie has opposed... besides the IWR and the Afghan surge, the Kyl-Lieberman amendment and the Syrian no-fly zone come to mind. Maybe you think Hillary's more hawkish stances are examples of good decisions, that's certainly your prerogative. Though I think it may be hard to sell Bernie's less hawkish positions as "bad decisions," at least to many Dems/progressives.
