Turning the other cheek in personal affairs is often virtuous, however, when it affects the rights of a nation to exist, or if that nation is inflicted by external injustice, turning the other cheek spells social suicide. 9:38-40
9:38 Believers, why is it that when it is said to you, 'March in the Way of Allah,' you linger with heaviness in the land? Are you content with this life rather than the Everlasting Life? Yet the enjoyment of this life in (comparison to) the Everlasting Life is little.
9:39 If you do not go forth, He will punish you with a painful punishment and replace you by another nation. You will in no way harm Him; for Allah has power over all things.
9:40 If you do not help him (Prophet Muhammad), Allah will help him as He helped him when he was driven out with one other (Abu Bakr) by the unbelievers. When the two were in the cave, he said to his companion, 'Do not sorrow, Allah is with us.' Then Allah caused His tranquility (sechina) to descend upon him and supported him with legions (of angels) you did not see, and He made the word of the unbelievers the lowest, and the Word of Allah is the highest. Allah is Mighty, Wise.
