JGN, Why we motivate our Indian army soldiers? why they are given galantry medals? why there are songs so many patriotic songs that encourages Indian soldiers to fight against enemies? So, If Quran does the same for its followers, you will mention it as violence teachings??
The first verse you mentioned above was revealed before the second war of ISLAM, when the enemies of Islam were preparing for war at mass level with superior arms and Muslims were struggling to survive and less in numbers. So the rumors of enemies prepration and size of their army being big were causing disapointment and despair in the Muslim army, at that time that verse was revealed to motivate them. But you mentioned it from no where specially excluding the context to make it look like Allah is ordering to go on fight and kill as a day to day routine...shame on you.
