This is pretty obscene, when it comes to violence, and libertarians are pretty annoyed by anybody who initiates violence

So, it does involve, you know, their foreign policy as well. When people do this, you know, the rejection of the violence has to be made, and with that I agree.”
I put blame on bad policy that we don’t fully understand, and we don’t understand what they’re doing because the people who are objecting to the foreign policy that we pursue, they do it from a different perspective,” Paul added. “They see us as attacking them, and killing innocent people, so yes, they, they have — this doesn’t justify, so don’t put those words in my mouth — it doesn’t justify, but it explains it.
