I remember videos of blowing up stuff in Afghanistan in 2001, and in Iraq in 2003.
With no long term intention to unconditionally obtain surrender from the enemies, or hold the territory, I am less impressed now.
This stuff is merely positive PR for Obama and for US military's fireworks.
But it is NOT a replacement for sound, long term foreign policy.
Besides Obama telegraphs all his moves, so the bad guys are well clear of the explosions, which destroy (American) military equipment abandoned by the fleeing cowardly Iraqi military.
