They are cowards. The day they feel empowered enough to fight our armed forces face-to-face in the daylight is the day to say the war is lost.
Propaganda comes in all sizes, shapes, forms.
Would declining to engage a better armed enemy, replete with superior communications, movement, body armor, air support and tanks be 'cowardly' or 'smart'?
Would it not be smarter (more effective) to attack the superior force's logistics, morale, command and control??
Anybody tangoing with a US Army or Marine Corps force in a direct 'combat arms' engagement is doomed to failure.
Learn up on 'asymmetric warfare'.
They have.
