Let's put this in perspective: Americans are terrified of terror. The Patriot Act was extremely popular with constituents. Invading Iraq similarly was popular (remember the ubiquitous flags on cars, lapels, homes?) through fear-mongering. Democrats, I'm sure you remember, were tarred and lost many an election because of the outrageous smear: "they're soft on (sub the perceived threat of the day)."
We also have a massive Defense Department. Obama has resisted calls for another Iraq War ("invade Syria and Iran!") and suffered for not doing so. It seems Americans enjoy the spectacle of killing that constant warfare provides, professing anguish at the deaths of our young men and women--- so ironically.
So, yes, Hillary isn't perfect, though let us hope she has learned lessons from Iraq. There is no evidence whatsoever that she counseled the President to invade either country I mentioned or to increase aggression.
You cannot expect perfection; I like Hillary's calm and reasoned rhetoric.
