# Do your share: The enemy from within is twice as dangerous

An Uncle Sam figure points at the viewer beside a boxed message that the enemy from within is twice as dangerous as the one from without, and asks readers to report all un-American activities to a superior officer or the FBI Director. The tell is the 'twice as dangerous' comparison paired with a direct pointing address, a fear-appeal with an instruction to report.
