Why Didn’t Krishna Show Duryodhana The Future

“All the sons of Dhritarashtra along with their allied kings, and Bhishma, Drona and Karna, and all our soldiers are rushing into Your mouths, their heads smashed by Your fearful teeth. I see that some are being crushed between Your teeth as well.” (Arjuna, Bhagavad-gita, 11.26-27)
