She's always run on an anti-war platform. She's saying both sides are wrong for it. Theres a pretty clear statement she put out calling Putin a war criminal. The point she's trying to make is that America is hypocritical at best to even point the finger, which in a lot of cases is true.
Americans don't want to talk about the bad things their country might do internationally though, so everyone calls her a Russian shill. Much more likely that, then there is any truth in what she is saying.
At least she wants to talk about our shortcomings honestly and try to solve them. The democrats won't even be honest with the public to begin with in most cases.
