Probably a calculated risk. A big part of the problem with ISIS is how so many people go wobbly over fear of publically opposing them. These guys are advertising because ISIS is advertising. They're challenging them toe to roe, mano a mano, in their face. This is necessary because two dozen guys is only the beginning. I believe they intend to start a movement. It will take a movement to make a difference. And to jump-start a serious movement, you have to go public. Look for Obama to try and publically squelch the group. If they play their cards right, that's when the movement will really start to take off. Just my two cents.

Many countries are canceling their passports for any one trying to join ISIS. I’m sure O’Venal will try that with these vets, though they are fighting AGAINST ISIS.
