Terrorist Attack in Germany?

Why can't Obama call a terrorsist attack a terrorist attack? When a jihadist shouts an Islamic statement and shoots an American soldier, why does President Obama have a hard time calling it a terrorist attack? The shooting in Germany was clearly a terrorist attack, is Obama so blind that he can't see that? or is their other reasons preventing him from decrying the recent attack on our military. Perhaps he is afraid of repercussion from radical sects of Islam, or maybe he sympathizes with jhadists. It really makes me wonder.
