Page 296 from the rulebook talks about dependant abilities (in this case the Strike).
An action, activity, free action, or reaction might call
on you to use a simpler ability—usually one of the
actions under Basic Actions on page 307—in a different
circumstance or with different effects. The dependent
ability still has its normal traits and is modified in any
ways listed in the more complex ability.
So while the drawing of the weapon is an Interaction action, the Strike is still just a Strike with all the accompanying traits and effects.
Wait, if it's an Interact action, does that means that it provokes an Attack of Opportunity? That seems problematic.
EDIT: Or do only Manipulate actions provoke? I'll have to check the book.
Trigger A creature within your reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it’s using.
An Interact action (page 207) has the Manipulate tag.
I don't see this as problematic, a Rogue can quickdraw and attack most people, but a trained fighter with his weapon out can react and cut him as he attempts it.
