BILL O'REILLY: ISIS should have been crushed a long time ago. If NATO and the rest of the world will join together that could happen quickly. But it is not happening and the 60 nation coalition that President Obama touts is a farce, it is doing nothing. So we can expect more Muslim killers like those in Canada to cause destruction almost everywhere. This is not going to stop until the world, the entire world, unites against terrorism, generated by Muslims.
