Ken believes we're in an exceptional period of tension with Iran. His articles range from "we're already at war" to "war is on the table". I don't believe Ken thinks Democrats are peaceniks. I do believe this frame he puts forward is created and pushed by the DNC for very obvious reasons. It gives Democrats an ability to differentiate themselves from Trump on a moral issue that is of substantial weight with everyone. The wording I used is consistent with this, "mere attempt for Democrats to reframe themselves as war-adverse peaceniks against a background of Trump".

If Trump really said/did these things,
Then he must really want war with Iran.
Ergo, Democrats are better.

That's a DNC tactic to establish themselves as a moral authority. My problem is it only works when you ignore what they themselves say and do -- which is always very similar.
