I am not American, but old enough to remember the situation around 9/11 well, and sure there was some of what you describe, but the discussion would still be around issue people percieve with pacifism and not accusing someone of actually supporting a dictatorship. No one seriously accused Germany of supporting Saddam Hussain for refusing to join the 2003 Irak war for example.
But if you go "uhm actually I am not a pacifist" and then name a highly selective list of conflicts you oppose like you did here (which included Syria btw), then you can't really complain about people pointing out the hypocricy of that and suspect that you based your opposition purely on a campist mindset (which given the list, is pretty obvious).
